VIRT-INSTALL(1)                     Virtual Machine Manager                    VIRT-INSTALL(1)

NAME
       virt-install - provision new virtual machines

SYNOPSIS
       virt-install [OPTION]...

DESCRIPTION
       virt-install is a command line tool for creating new KVM, Xen, or Linux container
       guests using the "libvirt" hypervisor management library.  See the EXAMPLES section at
       the end of this document to quickly get started.

       virt-install tool supports graphical installations using (for example) VNC or SPICE, as
       well as text mode installs over serial console. The guest can be configured to use one
       or more virtual disks, network interfaces, audio devices, physical USB or PCI devices,
       among others.

       The installation media can be held locally or remotely on NFS, HTTP, FTP servers. In
       the latter case "virt-install" will fetch the minimal files necessary to kick off the
       installation process, allowing the guest to fetch the rest of the OS distribution as
       needed. PXE booting, and importing an existing disk image (thus skipping the install
       phase) are also supported.

       Given suitable command line arguments, "virt-install" is capable of running completely
       unattended, with the guest 'kickstarting' itself too. This allows for easy automation
       of guest installs.

       Many arguments have sub options, specified like opt1=foo,opt2=bar, etc. Try --option=?
       to see a complete list of sub options associated with that argument, example: virt-
       install --disk=?

       Most options are not required. Minimum requirements are --name, --memory, guest storage
       (--disk or --filesystem), and an install option.

CONNECTING TO LIBVIRT
       --connect URI
           Connect to a non-default hypervisor. If this isn't specified, libvirt will try and
           choose the most suitable default.

           Some valid options here are:

           qemu:///system
               For creating KVM and QEMU guests to be run by the system libvirtd instance.
               This is the default mode that virt-manager uses, and what most KVM users want.

           qemu:///session
               For creating KVM and QEMU guests for libvirtd running as the regular user.

           xen:///
               For connecting to Xen.

           lxc:///
               For creating linux containers

GENERAL OPTIONS
       General configuration parameters that apply to all types of guest installs.

       -n NAME
       --name NAME
           Name of the new guest virtual machine instance. This must be unique amongst all
           guests known to the hypervisor on the connection, including those not currently
           active. To re-define an existing guest, use the virsh(1) tool to shut it down
           ('virsh shutdown') & delete ('virsh undefine') it prior to running "virt-install".

       --memory OPTIONS
           Memory to allocate for the guest, in MiB. This deprecates the -r/--ram option.  Sub
           options are available, like 'maxmemory', 'hugepages', 'hotplugmemorymax' and
           'hotplugmemoryslots'.  The memory parameter is mapped to <currentMemory> element,
           the 'maxmemory' sub-option is mapped to <memory> element and 'hotplugmemorymax' and
           'hotplugmemoryslots' are mapped to <maxMemory> element.

           To configure memory modules which can be hotunplugged see --memdev description.

           Use --memory=? to see a list of all available sub options. Complete details at
           <http://libvirt.org/formatdomain.html#elementsMemoryAllocation>

       --memorybacking OPTIONS
           This option will influence how virtual memory pages are backed by host pages.

           Use --memorybacking=? to see a list of all available sub options. Complete details
           at <http://libvirt.org/formatdomain.html#elementsMemoryBacking>

       --arch ARCH
           Request a non-native CPU architecture for the guest virtual machine.  If omitted,
           the host CPU architecture will be used in the guest.

       --machine MACHINE
           The machine type to emulate. This will typically not need to be specified for Xen
           or KVM, but is useful for choosing machine types of more exotic architectures.

       --metadata OPT=VAL,[...]
           Specify metadata values for the guest. Possible options include name, uuid, title,
           and description. This option deprecates -u/--uuid and --description.

           Use --metadata=? to see a list of all available sub options. Complete details at
           <http://libvirt.org/formatdomain.html#elementsMetadata>

       --events OPT=VAL,[...]
           Specify events values for the guest. Possible options include on_poweroff,
           on_reboot, and on_crash.

           Use --events=? to see a list of all available sub options. Complete details at
           <http://libvirt.org/formatdomain.html#elementsEvents>

       --resource OPT=VAL,[...]
           Specify resource partitioning for the guest.

           Use --resource=? to see a list of all available sub options. Complete details at
           <http://libvirt.org/formatdomain.html#resPartition>

       --sysinfo OPT=VAL,[...]
           Configure sysinfo/SMBIOS values exposed to the guest OS. '--sysinfo host' can be
           used to expose the host's SMBIOS info to the VM, otherwise values can be manually
           specified.

           Use --sysinfo=? to see a list of all available sub options. Complete details at
           <http://libvirt.org/formatdomain.html#elementsSysinfo>

       --qemu-commandline ARGS
           Pass options directly to the qemu emulator. Only works for the libvirt qemu driver.
           The option can take a string of arguments, for example:

             --qemu-commandline="-display gtk,gl=on"

           Environment variables are specified with 'env', for example:

             --qemu-commandline=env=DISPLAY=:0.1

           Complete details about the libvirt feature:
           <https://libvirt.org/drvqemu.html#qemucommand>

       --vcpus OPTIONS
           Number of virtual cpus to configure for the guest. If 'maxvcpus' is specified, the
           guest will be able to hotplug up to MAX vcpus while the guest is running, but will
           startup with VCPUS.

           CPU topology can additionally be specified with sockets, cores, and threads.  If
           values are omitted, the rest will be autofilled preferring sockets over cores over
           threads.

           'cpuset' sets which physical cpus the guest can use. "CPUSET" is a comma separated
           list of numbers, which can also be specified in ranges or cpus to exclude. Example:

               0,2,3,5     : Use processors 0,2,3 and 5
               1-5,^3,8    : Use processors 1,2,4,5 and 8

           If the value 'auto' is passed, virt-install attempts to automatically determine an
           optimal cpu pinning using NUMA data, if available.

           Use --vcpus=? to see a list of all available sub options. Complete details at
           <http://libvirt.org/formatdomain.html#elementsCPUAllocation>

       --numatune OPTIONS
           Tune NUMA policy for the domain process. Example invocations

               --numatune 1,2,3,4-7
               --numatune 1-3,5,mode=preferred

           Specifies the numa nodes to allocate memory from. This has the same syntax as
           "--vcpus cpuset=" option. mode can be one of 'interleave', 'preferred', or 'strict'
           (the default). See 'man 8 numactl' for information about each mode.

           Use --numatune=? to see a list of all available sub options. Complete details at
           <http://libvirt.org/formatdomain.html#elementsNUMATuning>

       --memtune OPTIONS
           Tune memory policy for the domain process. Example invocations

               --memtune 1000
               --memtune hard_limit=100,soft_limit=60,swap_hard_limit=150,min_guarantee=80

           Use --memtune=? to see a list of all available sub options. Complete details at
           <http://libvirt.org/formatdomain.html#elementsMemoryTuning>

           Tune blkio policy for the domain process. Example invocations

               --blkiotune 100
               --blkiotune weight=100,device_path=/dev/sdc,device_weight=200

           Use --blkiotune=? to see a list of all available sub options. Complete details at
           <http://libvirt.org/formatdomain.html#elementsBlockTuning>

       --cpu MODEL[,+feature][,-feature][,match=MATCH][,vendor=VENDOR],...
           Configure the CPU model and CPU features exposed to the guest. The only required
           value is MODEL, which is a valid CPU model as known to libvirt.

           Libvirt's feature policy values force, require, optional, disable, or forbid, or
           with the shorthand '+feature' and '-feature', which equal 'force=feature' and
           'disable=feature' respectively.

           If exact CPU model is specified virt-install will automatically copy CPU features
           available on the host to mitigate recent CPU speculative execution side channel and
           Microarchitectural Store Buffer Data security vulnerabilities.  This however will
           have some impact on performance and will break migration to hosts without security
           patches. In order to control this behavior there is a secure parameter. Possible
           values are on and off, with on as the default. It is highly recommended to leave
           this enabled and ensure all virtualization hosts have fully up to date microcode,
           kernel & virtualization software installed.

           Some examples:

           --cpu core2duo,+x2apic,disable=vmx
               Expose the core2duo CPU model, force enable x2apic, but do not expose vmx

           --cpu host
               Expose the host CPUs configuration to the guest. This enables the guest to take
               advantage of many of the host CPUs features (better performance), but may cause
               issues if migrating the guest to a host without an identical CPU.

           --cpu host-model-only
               Expose the nearest host CPU model configuration to the guest.  It is the best
               CPU which can be used for a guest on any of the hosts.

           --cpu cell0.memory=1234,cell0.cpus=0-3,cell1.memory=5678,cell1.cpus=4-7
               Example of specifying two NUMA cells. This will generate XML like:

                 <cpu>
                   <numa>
                     <cell cpus="0-3" memory="1234"/>
                     <cell cpus="4-7" memory="5678"/>
                   </numa>
                 </cpu>

           --cpu host-passthrough,cache.mode=passthrough
               Example of passing through the host cpu's cache information.

       --cputune OPTIONS
           Tune CPU parameters for the guest.

           Configure which of the host's physical CPUs the domain VCPU will be pinned to.
           Example invocation

               --cputune vpcupin0.vcpu=0,vpcupin0.cpuset=0-3,vpcupin1.vcpu=1,vpcupin1.cpuset=4-7

       --security type=TYPE[,label=LABEL][,relabel=yes|no]
           Configure domain security driver settings. Type can be either 'static' or
           'dynamic'. 'static' configuration requires a security LABEL. Specifying LABEL
           without TYPE implies static configuration.

           To have libvirt automatically apply your static label, you must specify
           relabel=yes. Otherwise disk images must be manually labeled by the admin, including
           images that virt-install is asked to create.

           <http://libvirt.org/formatdomain.html#seclabel>

       --features FEAT=on|off,...
           Set elements in the guests <features> XML on or off. Examples include acpi, apic,
           eoi, privnet, and hyperv features. Some examples:

           --features eoi=on
               Enable APIC PV EOI

           --features hyperv_vapic=on,hyperv_spinlocks=off
               Enable hypver VAPIC, but disable spinlocks

           --features kvm_hidden=on
               Allow the KVM hypervisor signature to be hidden from the guest

           --features pvspinlock=on
               Notify the guest that the host supports paravirtual spinlocks for example by
               exposing the pvticketlocks mechanism.

           --features gic_version=2
               This is relevant only for ARM architectures. Possible values are "host" or
               version number.

           --features smm=on
               This enables System Management Mode of hypervisor. Some UEFI firmwares may
               require this feature to be present. (QEMU supports SMM only with q35 machine
               type.)

       --clock offset=OFFSET,TIMER_OPT=VAL,...
           Configure the guest's <clock> XML. Some supported options:

           --clock offset=OFFSET
               Set the clock offset, ex. 'utc' or 'localtime'

           --clock TIMER_present=no
               Disable a boolean timer. TIMER here might be hpet, kvmclock, etc.

           --clock TIMER_tickpolicy=VAL
               Set a timer's tickpolicy value. TIMER here might be rtc, pit, etc. VAL might be
               catchup, delay, etc. Refer to the libvirt docs for all values.

INSTALLATION OPTIONS
       -c OPTIONS
       --cdrom OPTIONS
           File or device used as a virtual CD-ROM device.  It can be path to an ISO image or
           a URL from which to fetch/access a minimal boot ISO image. The URLs take the same
           format as described for the "--location" argument. If a cdrom has been specified
           via the "--disk" option, and neither "--cdrom" nor any other install option is
           specified, the "--disk" cdrom is used as the install media.

       -l LOCATION
       --location OPTIONS
           Distribution tree installation source. virt-install can recognize certain
           distribution trees and fetches a bootable kernel/initrd pair to launch the install.

           With libvirt 0.9.4 or later, network URL installs work for remote connections.
           virt-install will download kernel/initrd to the local machine, and then upload the
           media to the remote host. This option requires the URL to be accessible by both the
           local and remote host.

           --location allows things like --extra-args for kernel arguments, and using
           --initrd-inject. If you want to use those options with CDROM media, you have a few
           options:

           * Run virt-install as root and do --location ISO

           * Mount the ISO at a local directory, and do --location DIRECTORY

           * Mount the ISO at a local directory, export that directory over local http, and do
           --location http://localhost/DIRECTORY

           The "LOCATION" can take one of the following forms:

           http://host/path
               An HTTP server location containing an installable distribution image.

           ftp://host/path
               An FTP server location containing an installable distribution image.

           nfs:host:/path or nfs://host/path
               An NFS server location containing an installable distribution image. This
               requires running virt-install as root.

           DIRECTORY
               Path to a local directory containing an installable distribution image. Note
               that the directory will not be accessible by the guest after initial boot, so
               the OS installer will need another way to access the rest of the install media.

           ISO Mount the ISO and probe the directory. This requires running virt-install as
               root, and has the same VM access caveat as DIRECTORY.

       --pxe
           Use the PXE boot protocol to load the initial ramdisk and kernel for starting the
           guest installation process.

       --import
           Skip the OS installation process, and build a guest around an existing disk image.
           The device used for booting is the first device specified via "--disk" or
           "--filesystem".

       --livecd
           Specify that the installation media is a live CD and thus the guest needs to be
           configured to boot off the CDROM device permanently. It may be desirable to also
           use the "--disk none" flag in combination.

       -x EXTRA
       --extra-args OPTIONS
           Additional kernel command line arguments to pass to the installer when performing a
           guest install from "--location". One common usage is specifying an anaconda
           kickstart file for automated installs, such as --extra-args
           "ks=http://myserver/my.ks"

       --initrd-inject PATH
           Add PATH to the root of the initrd fetched with "--location". This can be used to
           run an automated install without requiring a network hosted kickstart file:

           --initrd-inject=/path/to/my.ks --extra-args "ks=file:/my.ks"

       --os-variant OS_VARIANT
           Optimize the guest configuration for a specific operating system (ex.  'fedora18',
           'rhel7', 'winxp'). While not required, specifying this options is HIGHLY
           RECOMMENDED, as it can greatly increase performance by specifying virtio among
           other guest tweaks.

           By default, virt-install will attempt to auto detect this value from the install
           media (currently only supported for URL installs). Autodetection can be disabled
           with the special value 'none'. Autodetection can be forced with the special value
           'auto'.

           Use the command "osinfo-query os" to get the list of the accepted OS variants.

       --boot BOOTOPTS
           Optionally specify the post-install VM boot configuration. This option allows
           specifying a boot device order, permanently booting off kernel/initrd with option
           kernel arguments, and enabling a BIOS boot menu (requires libvirt 0.8.3 or later)

           --boot can be specified in addition to other install options (such as --location,
           --cdrom, etc.) or can be specified on its own. In the latter case, behavior is
           similar to the --import install option: there is no 'install' phase, the guest is
           just created and launched as specified.

           Some examples:

           --boot cdrom,fd,hd,network,menu=on
               Set the boot device priority as first cdrom, first floppy, first harddisk,
               network PXE boot. Additionally enable BIOS boot menu prompt.

           --boot kernel=KERNEL,initrd=INITRD,kernel_args="console=/dev/ttyS0"
               Have guest permanently boot off a local kernel/initrd pair, with the specified
               kernel options.

           --boot kernel=KERNEL,initrd=INITRD,dtb=DTB
               Have guest permanently boot off a local kernel/initrd pair with an external
               device tree binary. DTB can be required for some non-x86 configurations like
               ARM or PPC

           --boot loader=BIOSPATH
               Use BIOSPATH as the virtual machine BIOS.

           --boot menu=on,useserial=on
               Enable the bios boot menu, and enable sending bios text output over serial
               console.

           --boot init=INITPATH
               Path to a binary that the container guest will init. If a root "--filesystem"
               has been specified, virt-install will default to /sbin/init, otherwise will
               default to /bin/sh.

           --boot uefi
               Configure the VM to boot from UEFI. In order for virt-install to know the
               correct UEFI parameters, libvirt needs to be advertising known UEFI binaries
               via domcapabilities XML, so this will likely only work if using properly
               configured distro packages.

           --boot
           loader=/.../OVMF_CODE.fd,loader_ro=yes,loader_type=pflash,nvram_template=/.../OVMF_VARS.fd,loader_secure=no
               Specify that the virtual machine use the custom OVMF binary as boot firmware,
               mapped as a virtual flash chip. In addition, request that libvirt instantiate
               the VM-specific UEFI varstore from the custom "/.../OVMF_VARS.fd" varstore
               template. This is the recommended UEFI setup, and should be used if --boot uefi
               doesn't know about your UEFI binaries. If your UEFI firmware supports Secure
               boot feature you can enable it via loader_secure.

           <http://libvirt.org/formatdomain.html#elementsOS>

       --idmap OPTIONS
           If the guest configuration declares a UID or GID mapping, the 'user' namespace will
           be enabled to apply these.  A suitably configured UID/GID mapping is a pre-
           requisite to make containers secure, in the absence of sVirt confinement.

           --idmap can be specified to enable user namespace for LXC containers

           Example:
               --idmap
           uid_start=0,uid_target=1000,uid_count=10,gid_start=0,gid_target=1000,gid_count=10

           <http://libvirt.org/formatdomain.html#elementsOSContainer>

STORAGE OPTIONS
       --disk OPTIONS
           Specifies media to use as storage for the guest, with various options. The general
           format of a disk string is

               --disk opt1=val1,opt2=val2,...

           The simplest invocation to create a new 10G disk image and associated disk device:

               --disk size=10

           virt-install will generate a path name, and place it in the default image location
           for the hypervisor. To specify media, the command can either be:

               --disk /some/storage/path[,opt1=val1]...

           or explicitly specify one of the following arguments:

           path
               A path to some storage media to use, existing or not. Existing media can be a
               file or block device.

               Specifying a non-existent path implies attempting to create the new storage,
               and will require specifying a 'size' value. Even for remote hosts, virt-install
               will try to use libvirt storage APIs to automatically create the given path.

               If the hypervisor supports it, path can also be a network URL, like
               http://example.com/some-disk.img . For network paths, they hypervisor will
               directly access the storage, nothing is downloaded locally.

           pool
               An existing libvirt storage pool name to create new storage on. Requires
               specifying a 'size' value.

           vol An existing libvirt storage volume to use. This is specified as
               'poolname/volname'.

           Other available options:

           device
               Disk device type. Value can be 'cdrom', 'disk', 'lun' or 'floppy'. Default is
               'disk'. If a 'cdrom' is specified, and no install method is chosen, the cdrom
               is used as the install media.

           boot_order
               Guest installation with multiple disks will need this parameter to boot
               correctly after being installed. A boot_order parameter will take values
               1,2,3,... Devices with lower value has higher priority.

           bus Disk bus type. Value can be 'ide', 'sata', 'scsi', 'usb', 'virtio' or 'xen'.
               The default is hypervisor dependent since not all hypervisors support all bus
               types.

           removable
               Sets the removable flag (/sys/block/$dev/removable on Linux). Only used with
               QEMU and bus=usb. Value can be 'on' or 'off'.

           readonly
               Set drive as readonly (takes 'on' or 'off')

           shareable
               Set drive as shareable (takes 'on' or 'off')

           size
               size (in GiB) to use if creating new storage

           sparse
               whether to skip fully allocating newly created storage. Value is 'yes' or 'no'.
               Default is 'yes' (do not fully allocate) unless it isn't supported by the
               underlying storage type.

               The initial time taken to fully-allocate the guest virtual disk (sparse=no)
               will be usually balanced by faster install times inside the guest. Thus use of
               this option is recommended to ensure consistently high performance and to avoid
               I/O errors in the guest should the host filesystem fill up.

           backing_store
               Path to a disk to use as the backing store for the newly created image.

           backing_format
               Disk image format of backing_store

           cache
               The cache mode to be used. The host pagecache provides cache memory.  The cache
               value can be 'none', 'writethrough', 'directsync', 'unsafe' or 'writeback'.
               'writethrough' provides read caching. 'writeback' provides read and write
               caching. 'directsync' bypasses the host page cache. 'unsafe' may cache all
               content and ignore flush requests from the guest.

           discard
               Whether discard (also known as "trim" or "unmap") requests are ignored or
               passed to the filesystem. The value can be either "unmap" (allow the discard
               request to be passed) or "ignore" (ignore the discard request). Since 1.0.6
               (QEMU and KVM only)

           format
               Disk image format. For file volumes, this can be 'raw', 'qcow2', 'vmdk', etc.
               See format types in <http://libvirt.org/storage.html> for possible values. This
               is often mapped to the driver_type value as well.

               If not specified when creating file images, this will default to 'qcow2'.

               If creating storage, this will be the format of the new image. If using an
               existing image, this overrides libvirt's format auto-detection.

           driver_name
               Driver name the hypervisor should use when accessing the specified storage.
               Typically does not need to be set by the user.

           driver_type
               Driver format/type the hypervisor should use when accessing the specified
               storage. Typically does not need to be set by the user.

           io  Disk IO backend. Can be either "threads" or "native".

           error_policy
               How guest should react if a write error is encountered. Can be one of "stop",
               "ignore", or "enospace"

           serial
               Serial number of the emulated disk device. This is used in linux guests to set
               /dev/disk/by-id symlinks. An example serial number might be: WD-WMAP9A966149

           startup_policy
               It defines what to do with the disk if the source file is not accessible.  See
               possible values in <http://www.libvirt.org/formatdomain.html#elementsDisks>,
               "startupPolicy" attribute of the <disk> element

           snapshot_policy
               Defines default behavior of the disk during disk snapshots.  See possible
               values in <http://www.libvirt.org/formatdomain.html#elementsDisks>, "snapshot"
               attribute of the <disk> element.

           See the examples section for some uses. This option deprecates -f/--file,
           -s/--file-size, --nonsparse, and --nodisks.

       --filesystem
           Specifies a directory on the host to export to the guest. The most simple
           invocation is:

               --filesystem /source/on/host,/target/point/in/guest

           Which will work for recent QEMU and linux guest OS or LXC containers. For QEMU, the
           target point is just a mounting hint in sysfs, so will not be automatically
           mounted.

           The following explicit options can be specified:

           type
               The type or the source directory. Valid values are 'mount' (the default) or
               'template' for OpenVZ templates.

           mode
               The access mode for the source directory from the guest OS. Only used with QEMU
               and type=mount. Valid modes are 'passthrough' (the default), 'mapped', or
               'squash'. See libvirt domain XML documentation for more info.

           source
               The directory on the host to share.

           target
               The mount location to use in the guest.

NETWORKING OPTIONS
       -w OPTIONS
       --network OPTIONS
           Connect the guest to the host network. The value for "NETWORK" can take one of 4
           formats:

           bridge=BRIDGE
               Connect to a bridge device in the host called "BRIDGE". Use this option if the
               host has static networking config & the guest requires full outbound and
               inbound connectivity  to/from the LAN. Also use this if live migration will be
               used with this guest.

           network=NAME
               Connect to a virtual network in the host called "NAME". Virtual networks can be
               listed, created, deleted using the "virsh" command line tool. In an unmodified
               install of "libvirt" there is usually a virtual network with a name of
               "default". Use a virtual network if the host has dynamic networking (eg
               NetworkManager), or using wireless. The guest will be NATed to the LAN by
               whichever connection is active.

           type=direct,source=IFACE[,source_mode=MODE]
               Direct connect to host interface IFACE using macvtap.

           user
               Connect to the LAN using SLIRP. Only use this if running a QEMU guest as an
               unprivileged user. This provides a very limited form of NAT.

           none
               Tell virt-install not to add any default network interface.

           If this option is omitted a single NIC will be created in the guest. If there is a
           bridge device in the host with a physical interface enslaved, that will be used for
           connectivity. Failing that, the virtual network called "default" will be used. This
           option can be specified multiple times to setup more than one NIC.

           Other available options are:

           model
               Network device model as seen by the guest. Value can be any nic model supported
               by the hypervisor, e.g.: 'e1000', 'rtl8139', 'virtio', ...

           mac Fixed MAC address for the guest; If this parameter is omitted, or the value
               "RANDOM" is specified a suitable address will be randomly generated. For Xen
               virtual machines it is required that the first 3 pairs in the MAC address be
               the sequence '00:16:3e', while for QEMU or KVM virtual machines it must be
               '52:54:00'.

           filterref
               Controlling firewall and network filtering in libvirt. Value can be any
               nwfilter defined by the "virsh" 'nwfilter' subcommands. Available filters can
               be listed by running 'virsh nwfilter-list', e.g.: 'clean-traffic',
               'no-mac-spoofing', ...

           virtualport_type
               The type of virtual port profile, one the following values

               "802.Qbg"
                   The following additional parameters are accepted

                   virtualport_managerid
                       The VSI Manager ID identifies the database containing the VSI type and
                       instance definitions. This is an integer value and the value 0 is
                       reserved.

                   virtualport_typeid
                       The VSI Type ID identifies a VSI type characterizing the network
                       access. VSI types are typically managed by network administrator.  This
                       is an integer value.

                   virtualport_typeidversion
                       The VSI Type Version allows multiple versions of a VSI Type. This is an
                       integer value.

                   virtualport_instanceid
                       The VSI Instance ID Identifier is generated when a VSI instance (i.e. a
                       virtual interface of a virtual machine) is created. This is a globally
                       unique identifier.

               "802.Qbh"
                   The following additional parameters are accepted

                   virtualport_profileid
                       The profile ID contains the name of the port profile that is to be
                       applied to this interface. This name is resolved by the port profile
                       database into the network parameters from the port profile, and those
                       network parameters will be applied to this interface.

               "openvswitch"
                   The following additional parameters are accepted

                   virtualport_profileid
                       The OpenVSwitch port profile for the interface

                   virtualport_interfaceid
                       A UUID to uniquely identify the interface. If omitted one will be
                       generated automatically

               "midonet"
                   The following additional parameters are accepted

                   virtualport_interfaceid
                       A UUID identifying the port in the network to which the interface will
                       be bound

           Use --network=? to see a list of all available sub options. Complete details at
           <http://libvirt.org/formatdomain.html#elementsNICS>

           This option deprecates -m/--mac, -b/--bridge, and --nonetworks

GRAPHICS OPTIONS
       If no graphics option is specified, "virt-install" will try to select the appropriate
       graphics if the DISPLAY environment variable is set, otherwise '--graphics none' is
       used.

       --graphics TYPE,opt1=arg1,opt2=arg2,...
           Specifies the graphical display configuration. This does not configure any virtual
           hardware, just how the guest's graphical display can be accessed.  Typically the
           user does not need to specify this option, virt-install will try and choose a
           useful default, and launch a suitable connection.

           General format of a graphical string is

               --graphics TYPE,opt1=arg1,opt2=arg2,...

           For example:

               --graphics vnc,password=foobar

           The supported options are:

           type
               The display type. This is one of:

               vnc

               Setup a virtual console in the guest and export it as a VNC server in the host.
               Unless the "port" parameter is also provided, the VNC server will run on the
               first free port number at 5900 or above. The actual VNC display allocated can
               be obtained using the "vncdisplay" command to "virsh" (or virt-viewer(1) can be
               used which handles this detail for the use).

               spice

               Export the guest's console using the Spice protocol. Spice allows advanced
               features like audio and USB device streaming, as well as improved graphical
               performance.

               Using spice graphic type will work as if those arguments were given:

                   --video qxl --channel spicevmc

               none

               No graphical console will be allocated for the guest. Guests will likely need
               to have a text console configured on the first serial port in the guest (this
               can be done via the --extra-args option). The command 'virsh console NAME' can
               be used to connect to the serial device.

           port
               Request a permanent, statically assigned port number for the guest console.
               This is used by 'vnc' and 'spice'

           tlsport
               Specify the spice tlsport.

           listen
               Address to listen on for VNC/Spice connections. Default is typically 127.0.0.1
               (localhost only), but some hypervisors allow changing this globally (for
               example, the qemu driver default can be changed in /etc/libvirt/qemu.conf).
               Use 0.0.0.0 to allow access from other machines.

               Use 'none' to specify that the display server should not listen on any port.
               The display server can be accessed only locally through libvirt unix socket
               (virt-viewer with --attach for instance).

               Use 'socket' to have the VM listen on a libvirt generated unix socket path on
               the host filesystem.

               This is used by 'vnc' and 'spice'

           keymap
               Request that the virtual console be configured to run with a specific keyboard
               layout. If the special value 'local' is specified, virt-install will attempt to
               configure to use the same keymap as the local system. A value of 'none'
               specifically defers to the hypervisor. Default behavior is hypervisor specific,
               but typically is the same as 'local'. This is used by 'vnc' and 'spice'.

           password
               Request a console password, required at connection time. Beware, this info may
               end up in virt-install log files, so don't use an important password. This is
               used by 'vnc' and 'spice'

           gl  Whether to use OpenGl accelerated rendering. Value is 'yes' or 'no'. This is
               used by 'spice'.

           rendernode
               DRM render node path to use. This is used when 'gl' is enabled.

           Use --graphics=? to see a list of all available sub options. Complete details at
           <http://libvirt.org/formatdomain.html#elementsGraphics>

           This deprecates the following options: --vnc, --vncport, --vnclisten, -k/--keymap,
           --sdl, --nographics

       --noautoconsole
           Don't automatically try to connect to the guest console. The default behaviour is
           to launch virt-viewer(1) to display the graphical console, or to run the "virsh"
           "console" command to display the text console. Use of this parameter will disable
           this behaviour.

VIRTUALIZATION OPTIONS
       Options to override the default virtualization type choices.

       -v
       --hvm
           Request the use of full virtualization, if both para & full virtualization are
           available on the host. This parameter may not be available if connecting to a Xen
           hypervisor on a machine without hardware virtualization support. This parameter is
           implied if connecting to a QEMU based hypervisor.

       -p
       --paravirt
           This guest should be a paravirtualized guest. If the host supports both para & full
           virtualization, and neither this parameter nor the "--hvm" are specified, this will
           be assumed.

       --container
           This guest should be a container type guest. This option is only required if the
           hypervisor supports other guest types as well (so for example this option is the
           default behavior for LXC and OpenVZ, but is provided for completeness).

       --virt-type
           The hypervisor to install on. Example choices are kvm, qemu, or xen.  Available
           options are listed via 'virsh capabilities' in the <domain> tags.

           This deprecates the --accelerate option, which is now the default behavior. To
           install a plain QEMU guest, use '--virt-type qemu'

DEVICE OPTIONS
       All devices have a set of address.* options for configuring the particulars of the
       device's address on its parent controller or bus.  See
       "http://libvirt.org/formatdomain.html#elementsAddress" for details.

       --controller OPTIONS
           Attach a controller device to the guest. TYPE is one of: ide, fdc, scsi, sata,
           virtio-serial, or usb.

           Controller also supports the special values usb2 and usb3 to specify which version
           of the USB controller should be used (version 2 or 3).

           model
               Controller model.  These may vary according to the hypervisor and its version.
               Most commonly used models are e.g. auto, virtio-scsi for the scsi controller,
               ehci or none for the usb controller.  For full list and further details on
               controllers/models, see
               "http://libvirt.org/formatdomain.html#elementsControllers".

           address
               Shorthand for setting a manual PCI address from an lscpi style string.  The
               preferred method for setting this is using the address.* parameters.

           index
               A decimal integer describing in which order the bus controller is encountered,
               and to reference the controller bus.

           master
               Applicable to USB companion controllers, to define the master bus startport.

           Examples:

           --controller usb,model=ich9-ehci1,address=0:0:4.0,index=0
               Adds a ICH9 EHCI1 USB controller on PCI address 0:0:4.0

           --controller usb,model=ich9-uhci2,address=0:0:4.7,index=0,master=2
               Adds a ICH9 UHCI2 USB companion controller for the previous master controller,
               ports start from port number 2.

               The parameter multifunction='on' will be added automatically to the proper
               device (if needed).  This applies to all PCI devices.

           <http://libvirt.org/formatdomain.html#elementsControllers>

       --input OPTIONS
           Attach an input device to the guest. Example input device types are mouse, tablet,
           or keyboard.

           Use --input=? to see a list of all available sub options. Complete details at
           <http://libvirt.org/formatdomain.html#elementsInput>

       --hostdev OPTIONS
       --host-device OPTIONS
           Attach a physical host device to the guest. Some example values for HOSTDEV:

           --hostdev pci_0000_00_1b_0
               A node device name via libvirt, as shown by 'virsh nodedev-list'

           --hostdev 001.003
               USB by bus, device (via lsusb).

           --hostdev 0x1234:0x5678
               USB by vendor, product (via lsusb).

           --hostdev 1f.01.02
               PCI device (via lspci).

           Use --hostdev=? to see a list of all available sub options. Complete details at
           <http://libvirt.org/formatdomain.html#elementsHostDev>

       --sound MODEL
           Attach a virtual audio device to the guest. MODEL specifies the emulated sound card
           model. Possible values are ich6, ich9, ac97, es1370, sb16, pcspk, or default.
           'default' will try to pick the best model that the specified OS supports.

           This deprecates the old --soundhw option.

           Use --sound=? to see a list of all available sub options. Complete details at
           <http://libvirt.org/formatdomain.html#elementsSound>

       --watchdog MODEL[,action=ACTION]
           Attach a virtual hardware watchdog device to the guest. This requires a daemon and
           device driver in the guest. The watchdog fires a signal when the virtual machine
           appears to hung. ACTION specifies what libvirt will do when the watchdog fires.
           Values are

           reset
               Forcefully reset the guest (the default)

           poweroff
               Forcefully power off the guest

           pause
               Pause the guest

           none
               Do nothing

           shutdown
               Gracefully shutdown the guest (not recommended, since a hung guest probably
               won't respond to a graceful shutdown)

           MODEL is the emulated device model: either i6300esb (the default) or ib700.  Some
           examples:

           Use the recommended settings:

           --watchdog default

           Use the i6300esb with the 'poweroff' action

           --watchdog i6300esb,action=poweroff

           Use --watchdog=? to see a list of all available sub options. Complete details at
           <http://libvirt.org/formatdomain.html#elementsWatchdog>

       --parallel OPTIONS
       --serial OPTIONS
           Specifies a serial device to attach to the guest, with various options. The general
           format of a serial string is

               --serial type,opt1=val1,opt2=val2,...

           --serial and --parallel devices share all the same options, unless otherwise noted.
           Some of the types of character device redirection are:

           --serial pty
               Pseudo TTY. The allocated pty will be listed in the running guests XML
               description.

           --serial dev,path=HOSTPATH
               Host device. For serial devices, this could be /dev/ttyS0. For parallel
               devices, this could be /dev/parport0.

           --serial file,path=FILENAME
               Write output to FILENAME.

           --serial pipe,path=PIPEPATH
               Named pipe (see pipe(7))

           --serial tcp,host=HOST:PORT,mode=MODE,protocol=PROTOCOL
               TCP net console. MODE is either 'bind' (wait for connections on HOST:PORT) or
               'connect' (send output to HOST:PORT), default is 'bind'. HOST defaults to
               '127.0.0.1', but PORT is required. PROTOCOL can be either 'raw' or 'telnet'
               (default 'raw'). If 'telnet', the port acts like a telnet server or client.
               Some examples:

               Wait for connections on any address, port 4567:

               --serial tcp,host=0.0.0.0:4567

               Connect to localhost, port 1234:

               --serial tcp,host=:1234,mode=connect

               Wait for telnet connection on localhost, port 2222. The user could then connect
               interactively to this console via 'telnet localhost 2222':

               --serial tcp,host=:2222,mode=bind,protocol=telnet

           --serial udp,host=CONNECT_HOST:PORT,bind_host=BIND_HOST:BIND_PORT
               UDP net console. HOST:PORT is the destination to send output to (default HOST
               is '127.0.0.1', PORT is required). BIND_HOST:BIND_PORT is the optional local
               address to bind to (default BIND_HOST is 127.0.0.1, but is only set if
               BIND_PORT is specified). Some examples:

               Send output to default syslog port (may need to edit /etc/rsyslog.conf
               accordingly):

               --serial udp,host=:514

               Send output to remote host 192.168.10.20, port 4444 (this output can be read on
               the remote host using 'nc -u -l 4444'):

               --serial udp,host=192.168.10.20:4444

           --serial unix,path=UNIXPATH,mode=MODE
               Unix socket, see unix(7). MODE has similar behavior and defaults as --serial
               tcp,mode=MODE

           Use --serial=? or --parallel=? to see a list of all available sub options. Complete
           details at <http://libvirt.org/formatdomain.html#elementsCharSerial> and
           <http://libvirt.org/formatdomain.html#elementsCharParallel>

       --channel
           Specifies a communication channel device to connect the guest and host machine.
           This option uses the same options as --serial and --parallel for specifying the
           host/source end of the channel. Extra 'target' options are used to specify how the
           guest machine sees the channel.

           Some of the types of character device redirection are:

           --channel SOURCE,target_type=guestfwd,target_address=HOST:PORT
               Communication channel using QEMU usermode networking stack. The guest can
               connect to the channel using the specified HOST:PORT combination.

           --channel SOURCE,target_type=virtio[,name=NAME]
               Communication channel using virtio serial (requires 2.6.34 or later host and
               guest). Each instance of a virtio --channel line is exposed in the guest as
               /dev/vport0p1, /dev/vport0p2, etc. NAME is optional metadata, and can be any
               string, such as org.linux-kvm.virtioport1.  If specified, this will be exposed
               in the guest at /sys/class/virtio-ports/vport0p1/NAME

           --channel spicevmc,target_type=virtio[,name=NAME]
               Communication channel for QEMU spice agent, using virtio serial (requires
               2.6.34 or later host and guest). NAME is optional metadata, and can be any
               string, such as the default com.redhat.spice.0 that specifies how the guest
               will see the channel.

           Use --channel=? to see a list of all available sub options. Complete details at
           <http://libvirt.org/formatdomain.html#elementsCharChannel>

       --console
           Connect a text console between the guest and host. Certain guest and hypervisor
           combinations can automatically set up a getty in the guest, so an out of the box
           text login can be provided (target_type=xen for xen paravirt guests, and possibly
           target_type=virtio in the future).

           Example:

           --console pty,target_type=virtio
               Connect a virtio console to the guest, redirected to a PTY on the host.  For
               supported guests, this exposes /dev/hvc0 in the guest. See
               http://fedoraproject.org/wiki/Features/VirtioSerial for more info. virtio
               console requires libvirt 0.8.3 or later.

           Use --console=? to see a list of all available sub options. Complete details at
           <http://libvirt.org/formatdomain.html#elementsCharConsole>

       --video OPTIONS
           Specify what video device model will be attached to the guest. Valid values for
           VIDEO are hypervisor specific, but some options for recent kvm are cirrus, vga,
           qxl, virtio, or vmvga (vmware).

           Use --video=? to see a list of all available sub options. Complete details at
           <http://libvirt.org/formatdomain.html#elementsVideo>

       --smartcard MODE[,OPTIONS]
           Configure a virtual smartcard device.

           Mode is one of host, host-certificates, or passthrough. Additional options are:

           type
               Character device type to connect to on the host. This is only applicable for
               passthrough mode.

           An example invocation:

           --smartcard passthrough,type=spicevmc
               Use the smartcard channel of a SPICE graphics device to pass smartcard info to
               the guest

           Use --smartcard=? to see a list of all available sub options. Complete details at
           <http://libvirt.org/formatdomain.html#elementsSmartcard>

       --redirdev BUS[,OPTIONS]
           Add a redirected device.

           type
               The redirection type, currently supported is tcp or spicevmc.

           server
               The TCP server connection details, of the form 'server:port'.

           Examples of invocation:

           --redirdev usb,type=tcp,server=localhost:4000
               Add a USB redirected device provided by the TCP server on 'localhost' port
               4000.

           --redirdev usb,type=spicevmc
               Add a USB device redirected via a dedicated Spice channel.

           Use --redirdev=? to see a list of all available sub options. Complete details at
           <http://libvirt.org/formatdomain.html#elementsRedir>

       --memballoon MODEL
           Attach a virtual memory balloon device to the guest. If the memballoon device needs
           to be explicitly disabled, MODEL='none' is used.

           MODEL is the type of memballoon device provided. The value can be 'virtio', 'xen'
           or 'none'.  Some examples:

           Use the recommended settings:

           --memballoon virtio

           Do not use memballoon device:

           --memballoon none

           Use --memballoon=? to see a list of all available sub options. Complete details at
           <http://libvirt.org/formatdomain.html#elementsMemBalloon>

       --tpm TYPE[,OPTIONS]
           Configure a virtual TPM device.

           Type must be passthrough. Additional options are:

           model
               The device model to present to the guest operating system. Model must be tpm-
               tis.

           An example invocation:

           --tpm passthrough,model=tpm-tis
               Make the host's TPM accessible to a single guest.

           --tpm /dev/tpm
               Convenience option for passing through the hosts TPM.

           Use --tpm=? to see a list of all available sub options. Complete details at
           <http://libvirt.org/formatdomain.html#elementsTpm>

       --rng TYPE[,OPTIONS]
           Configure a virtual RNG device.

           Type can be random or egd.

           If the specified type is random then these values must be specified:

           backend_device
               The device to use as a source of entropy.

           Whereas, when the type is egd, these values must be provided:

           backend_host
               Specify the host of the Entropy Gathering Daemon to connect to.

           backend_service
               Specify the port of the Entropy Gathering Daemon to connect to.

           backend_type
               Specify the type of the connection: tcp or udp.

           backend_mode
               Specify the mode of the connection.  It is either 'bind' (wait for connections
               on HOST:PORT) or 'connect' (send output to HOST:PORT).

           backend_connect_host
               Specify the remote host to connect to when the specified backend_type is udp
               and backend_mode is bind.

           backend_connect_service
               Specify the remote service to connect to when the specified backend_type is udp
               and backend_mode is bind.

           An example invocation:

           --rng egd,backend_host=localhost,backend_service=8000,backend_type=tcp
               Connect to localhost to the TCP port 8000 to get entropy data.

           --rng /dev/random
               Use the /dev/random device to get entropy data, this form implicitly uses the
               "random" model.

               Use --rng=? to see a list of all available sub options. Complete details at
               <http://libvirt.org/formatdomain.html#elementsRng>

       --panic MODEL[,OPTS]
           Attach a panic notifier device to the guest. For the recommended settings, use:

           --panic default

           Use --panic=? to see a list of all available sub options. Complete details at
           <http://libvirt.org/formatdomain.html#elementsPanic>

       --memdev OPTS
           Add a memory module to a guest which can be hotunplugged. To add a memdev you need
           to configure hotplugmemory and NUMA for a guest.

           Use --memdev=? to see a list of all available sub options. Complete details at
           <http://libvirt.org/formatdomain.html#elementsMemory>.

MISCELLANEOUS OPTIONS
       -h
       --help
           Show the help message and exit

       --version
           Show program's version number and exit

       --autostart
           Set the autostart flag for a domain. This causes the domain to be started on host
           boot up.

       --transient
           Use --import or --boot and --transient if you want a transient libvirt VM.  These
           VMs exist only until the domain is shut down or the host server is restarted.
           Libvirt forgets the XML configuration of the VM after either of these events.  Note
           that the VM's disks will not be deleted.  See:
           <http://wiki.libvirt.org/page/VM_lifecycle#Transient_guest_domains_vs_Persistent_guest_domains>

       --print-xml [STEP]
           Print the generated XML of the guest, instead of defining it. By default this WILL
           do storage creation (can be disabled with --dry-run). This option implies --quiet.

           If the VM install has multiple phases, by default this will print all generated
           XML. If you want to print a particular step, use --print-xml 2 (for the second
           phase XML).

       --noreboot
           Prevent the domain from automatically rebooting after the install has completed.

       --wait WAIT
           Amount of time to wait (in minutes) for a VM to complete its install.  Without this
           option, virt-install will wait for the console to close (not necessarily indicating
           the guest has shutdown), or in the case of --noautoconsole, simply kick off the
           install and exit. Any negative value will make virt-install wait indefinitely, a
           value of 0 triggers the same results as noautoconsole. If the time limit is
           exceeded, virt-install simply exits, leaving the virtual machine in its current
           state.

       --dry-run
           Proceed through the guest creation process, but do NOT create storage devices,
           change host device configuration, or actually teach libvirt about the guest.  virt-
           install may still fetch install media, since this is required to properly detect
           the OS to install.

       --check
           Enable or disable some validation checks. Some examples are warning about using a
           disk that's already assigned to another VM (--check path_in_use=on|off), or warning
           about potentially running out of space during disk allocation (--check
           disk_size=on|off). Most checks are performed by default.

       -q
       --quiet
           Only print fatal error messages.

       -d
       --debug
           Print debugging information to the terminal when running the install process.  The
           debugging information is also stored in "~/.cache/virt-manager/virt-install.log"
           even if this parameter is omitted.

EXAMPLES
       Install a Fedora 9 plain QEMU guest, using LVM partition, virtual networking, booting
       from PXE, using VNC server/viewer, with virtio-scsi disk

         # virt-install \
              --connect qemu:///system \
              --name demo \
              --memory 500 \
              --disk path=/dev/HostVG/DemoVM,bus=scsi \
              --controller virtio-scsi \
              --network network=default \
              --virt-type qemu \
              --graphics vnc \
              --os-variant fedora9

       Run a Live CD image under Xen fullyvirt, in diskless environment

         # virt-install \
              --hvm \
              --name demo \
              --memory 500 \
              --disk none \
              --livecd \
              --graphics vnc \
              --cdrom /root/fedora7live.iso

       Run /usr/bin/httpd in a linux container guest (LXC). Resource usage is capped at 512
       MiB of ram and 2 host cpus:

         # virt-install \
               --connect lxc:/// \
               --name httpd_guest \
               --memory 512 \
               --vcpus 2 \
               --init /usr/bin/httpd

       Start a linux container guest(LXC) with a private root filesystem, using /bin/sh as
       init.  Container's root will be under host dir /home/LXC.  The host dir "/home/test"
       will be mounted at "/mnt" dir inside container:

         # virt-install \
               --connect lxc:/// \
               --name container \
               --memory 128 \
               --filesystem /home/LXC,/ \
               --filesystem /home/test,/mnt \
               --init /bin/sh

       Install a paravirtualized Xen guest, 500 MiB of RAM, a 5 GiB of disk, and Fedora Core 6
       from a web server, in text-only mode, with old style --file options:

         # virt-install \
              --paravirt \
              --name demo \
              --memory 500 \
              --disk /var/lib/xen/images/demo.img,size=6 \
              --graphics none \
              --location http://download.fedora.redhat.com/pub/fedora/linux/core/6/x86_64/os/

       Create a guest from an existing disk image 'mydisk.img' using defaults for the rest of
       the options.

         # virt-install \
              --name demo \
              --memory 512 \
              --disk /home/user/VMs/mydisk.img \
              --import

       Start serial QEMU ARM VM, which requires specifying a manual kernel.

         # virt-install \
              --name armtest \
              --memory 1024 \
              --arch armv7l --machine vexpress-a9 \
              --disk /home/user/VMs/myarmdisk.img \
              --boot kernel=/tmp/my-arm-kernel,initrd=/tmp/my-arm-initrd,dtb=/tmp/my-arm-dtb,kernel_args="console=ttyAMA0 rw root=/dev/mmcblk0p3" \
              --graphics none
