We recently uploaded a 6.5 kernel into our repositories, it will be used as new default kernel in the next Proxmox VE 8.1 point release (Q4'2023), following our tradition of upgrading the Proxmox VE kernel to match the current Ubuntu version until we reach an (Ubuntu) LTS release.
We have run this kernel on some parts of our test setups over the last few weeks without any notable issues, at least none that we addressed before this first public release.
How to install:
Please note:
Feedback about how the new kernel performs in any of your setups is welcome!
Please provide basic details like CPU model, storage types used, ZFS as root file system, and the like, for both positive feedback or if you ran into some issues, where the 6.5 kernel seems to be the cause.

How to install:
- Ensure that either the pve-no-subscription or pvetest repository is set up correctly.
You can do so via CLI text-editor or using the web UI under Node -> Repositories apt update
apt full-upgrade
# to get ZFS 2.2 user space packagesapt install pve-kernel-6.5
- reboot
Please note:
- We will provide this new kernel soon on the
pve-no-subscription
repository. While the new kernel is currently only opt-in, and newer ZFS user space packages are compatible with older kernel modules, we still wanted to avoid rushing the ZFS user-space out to no-subscription. - The current 6.2 kernel is still supported and will still receive updates until at least end of year, but it's unlikely that the ZFS module will be updated in the 6.2 kernel anymore.
- There were many changes, for improved hardware support, performance improvements in file system, but really all over the place, and enabling the Multi-Gen LRU by default. For a more complete list of changes we recommend checking out the kernel-newbies sites for 6.3, 6.4 and 6.5.
- The kernel is also available on the test repository of Proxmox Backup Server and Proxmox Mail Gateway.
- If you're unsure, we recommend continuing to use the 6.2-based kernel for now.
