openstack 手工制作镜像
一 摘要
本文主要记录openstack 安装完成后，手工制作相关镜像。主要是在mitaka和ussuri 版本上测试验证。
二 环境信息
(一) openstack 版本
三 镜像制作
（一）linux 系列镜像制作
3.1.1 通过命令的方式制作（mitaka\ussuri 版本上均验证）
首先准备 CentOS-7-x86_64-DVD-1611.iso 镜像文件，此处存放在该目录下/root/software/os/
3.1.1.1 创建虚拟磁盘
我这里建了一个2000G 的虚拟磁盘，太大了，大家可以根据实际需求调整。
[root@ussuritmp os]# mkdir -p /root/software/makeglance
[root@ussuritmp os]# qemu-img create -f qcow2 /root/software/makeglance/centos7.3min2000G.qcow2 2000G
Formatting '/root/software/makeglance/centos7.3min2000G.qcow2', fmt=qcow2 size=2147483648000 cluster_size=65536 lazy_refcounts=off refcount_bits=16
3.1.1.2 系统安装
[root@ussuritmp os]# /usr/libexec/qemu-kvm -m 1024 -cdrom /root/software/os/CentOS-7-x86_64-DVD-1611.iso -drive file=/root/software/makeglance/centos7.3min2000G.qcow2 -boot menu=on --nographic -vnc :3
SeaBIOS (version 1.11.1-4.module_el8.1.0+248+298dec18)
iPXE (http://ipxe.org) 00:03.0 C980 PCI2.10 PnP PMM+3FF91570+3FED1570 C980
Press ESC for boot menu.
Booting from Hard Disk...
Boot failed: not a bootable disk
Booting from Floppy...
Boot failed: could not read the boot disk
Booting from DVD/CD...
执行完上面，然后通过vnc 连接 机器 连接地址是是机器IP:3,正常安装操作系统即可。
3.1.1.3 镜像制作
系统安装好之后，使用命令制作镜像即可。然后在前台页面里就能看到镜像了。
[root@ussuritmp makeglance]# source /etc/kolla/admin-openrc.sh
[root@ussuritmp makeglance]# openstack image create "centos7.3min2000G.qcow2" --file /root/software/makeglance/centos7.3min2000G.qcow2 --disk-format qcow2 --container-format bare --public
