proxmox新版本特性查询
proxmox是开源virtualization的扛鼎之作，一直在持续更新中，如果想查询新版本的新功能和特性，可以翻阅wiki：https://pve.proxmox.com/wiki/Roadmap#Proxmox_VE_6.2
我来摘录下6.2的更新内容：
Proxmox VE 6.2
Released 12. May 2020
Based on Debian Buster (10.4)
Ceph Nautilus (14.2.9)
Kernel 5.4 LTS
LXC 4.0
Qemu 5.0
ZFS 0.8.3
Web interface
Allow to deploy DNS based Let's Encrypt (ACME) certificates
Allow admins to see the full granted permission/privilege tree for a user
Add experimental Software Defined Network (SDN) GUI and documentation, based on modern mainline Linux Kernel network technology
Allow to collapse the Notes sub-panel in the guest summary panels. One can do this permanently or automatically if empty through the user settings.
Add 'Creation Date' column for storage content, allowing one, for example, to comfortably find backups from a certain date
Add device node creation to Container feature selection
Full support for up to 8 corosync links
Automatic guest console reload on VM/CT startup
Add Arabic translation
Allow seamlessly changing the language, without logging out and logging in again
Container
LXC 4.0.2 and lxcfs 4.0.3 with initial full cgroupv2 support by Proxmox VE
Improve support for modern systemd based Containers
Improve default settings to support hundreds to thousands* of parallel running Containers per node (* thousands only with simple distributions like Alpine Linux)
Allow creating templates on directory-based storage
Backup/Restore
Support for the highly efficient and fast Zstandard (zstd) compression
Improvements to the HA stack
Allow to destroy virtual guests under HA control when purge is set
QEMU
Fixed EFI disk behavior on block-based storage (see known issues)
VirtIO Random Number Generator (RNG) support for VMs
Custom CPU types with user-defined flags and QEMU/KVM settings
Improved machine type versioning and compatibility checks
Various stability fixes, especially for backups and IO-Threads
Migration:
Enable support for Live-Migration with replicated disks
Allow specifying target storage for offline mode
Allow specifying multiple source-target storage pairs (for now, CLI only)
Improve behavior with unused disks
Secure live-migration with local disks
General improvements for virtual guests
Handle ZFS volumes with non-standard mount point correctly
Cluster
Improve lock contention during high frequency config modifications
Add versioning for cluster join
Enable full support for up to 8 corosync links
Ceph
Easier uninstall process, better informing which actions need to be taken.
Storage
Storage migration: introduce allow-rename option and return new volume ID if a volume with the same ID is already allocated on the target storage
Support the 'snippet' content type for GlusterFS storage
Bandwidth limitations are now also available for SAMBA/CIFS based storage
Handle ZFS volumes with non-standard mount point correctly
Improve metadata calculation when creating a new LVM-Thin pool
Improve parsing of NVMe wearout metrics
User and permission management
LDAP Sync users and groups automatically into Proxmox VE
LDAP mode LDAP+STARTTLS
Allow to add and manage authentication realms through the 'pveum' CLI tool
Full support and integration for API Tokens
Shared or separated privileges
Token lifetime
Revoke it anytime without impacting your user login
Documentation
Update hypervisor migration guide in the wiki
Reducing number of Ceph placement groups is possible
Improve layout, use a left-side based table-of-content
Various improvements
Firewall: make config parsing more robust and improve ICMP-type filtering
Known Issues with OVMF/UEFI disks
An EFI disk on a storage which doesn't allow for small (128 KB) images (for example: CEPH, ZFS, LVM(thin)), was not correctly mapped to the VM. While fixed now, such existing setup may need manual intervention:
You do not have to do anything if your EFI disks is using qcow2 or "raw" on a file based storage.
Before the upgrade, make sure that on your ESP, the EFI boot binary exists at \EFI\BOOT\BOOTX64.EFI (the default EFI Boot fallback).
Windows and some Linux VMs using systemd-boot should do that automatically
If you already upgraded and it does not boot, see OVMF/UEFI Boot Entries on how to recreate the boot entry via the OVMF Boot Menu
