Proxmox has released a new major version for it’s virtualization Platform: V9.0.

The release Notes can be found here, the new features include:

  • Based on Debian 13 “Trixie” but uses Linux kernel 6.14.8-2 as new stable default
  • VM snapshots on thick-provisioned LVM storages
  • HA rules for node and resource affinity
  • Fabrics for the Software-Defined Networking stack
  • Modernized mobile web interface
  • Comprehensive upgrade guide from 8 to 9
  • ZFS 2.3.3 with support for adding new devices to RAIDZ pools without downtime
  • QEMU 10.0.2, LXC 6.0.4, Ceph Squid 19.2.3
  • and much more…

Be aware: This is the first release of a new major version of Proxmox. We have not yet much experience in fixing / debugging V9.0 (although we are already running it in production there might be some hickups).

On the first glance we did not find showstoppers – but as this release is just a few hours old we might into bigger issues at a later time. The release is based on Debian 13 (which is in release candidate status right now – if applicable: check back with your CISO / CSO first!).

One thing we can for sure tell: The mobile UI is a big step forward!

If all goes well we will contact our customers within the next few weeks to plan updates.
