Proxmox VE 6.2 is now out. This is a big deal for the community of users who are looking to utilize the latest open virtualization solution. Proxmox VE 6.2 is a dot release so we get some new features, but much of the core functionality remains the same. Examples include updated Live Migration support with replicated disks (storage replication with zfs) with KVM/ QEMU is an example of a new feature as are the updates to the Ceph testing and uninstall processes. LXC saw new updates for that container solution supported by Proxmox VE. We also see Zstandard (zstd) compression being utilized for backups.

New Feature Highlights for Proxmox VE 6.2

Advanced options for the web-based management interface:

  • Proxmox VE implements built-in validation of domains for Let’s Encrypt TLS certificates via the DNS-based challenge mechanism, in addition to the already existing HTTP-based validation mode.

  • Full support for up to eight corosync network links is available. The more links are used, the higher the cluster availability.
  • In the storage content view, administrators can now filter the stored data with the new column ‘Creation Date’ which, for example, simplifies to search for a backup from a certain date.

  • The language of the web interface can be seamlessly changed without the need to restart the session. An Arabic translation has been added and thus Proxmox VE supports 20 languages in total.

Final Words

Overall the Proxmox VE dot releases have become a lot more stable. The big question is whether Proxmox VE will ever add the major share and user management features FreeNAS / TrueNAS has so that Proxmox VE will become the all-in-one solution for those looking towards open source virtualization and storage. Proxmox VE is very close with the new 6.2 release from becoming an absolute category killer in the space. If you are looking to switch a small virtualization cluster from VMware or Microsoft Hyper-V to Proxmox VE to save on licensing costs during the downturn, it is a very easy process these days with both a WebGUI as well as a CLI using open source tools. If you are even thinking about it in the future, this is a good opportunity to download the newest version and give it a try.


  1. Definitely need to update for the live migration with zfs replication functionality. Been waiting for that. Hoping it works like I think it does.

  2. What is the recommended solution to backup large proxmox VMs? Last I checked their backup solutions were very inefficient.

  3. How big of VMs Brendon are “big”.

    I mean, snapshot to compressed backup is really easy in 2020 right?

  4. John Leee.
    Snapshot is not enough.. So now it depends on what you use.. if you use LXC.. and database in a container.. then you have to tell the DB to flush everything otherwise you might loose the last few commits. Using the KVM and something like windows insode is even worse.. there you should flush the whole filesystem when taking a snapshot.. or risk runing checkdisk in case of restore.. or having corruped MSSQL db or something like that.

  5. Proxmox already does consistent snapshots. I tested it many times both , i could restore backups reliably.

  6. Also, ZFS on Linux 0.8.4 has come to Proxmox. It accelerates AES-GCM encryption speed significantly.
