your kernel is quite old, last version is pve-kernel-5.15.108-1-pve

do update first, maybe this bug is fixed.

 

[floryn29x]

I'm not an expert in proxmox, can you please suggest the steps to do a safe update
thank you

you can do it through the gui (node->updates).

Also check that if you don't have a license, to configure the no-subscription repository. (same place in the gui)

 

[floryn29x]

are the following commands enough?

apt update
apt dist-upgrade
reboot

 

[spirit]

yes if you don't want to use the gui.
(but double check the repos first)

Hi,
yes this should be fixed since a long time. From the Proxmox VE 7.2 release notes:

Certain systems may need to work around a HW issue with TDP (two-dimensional paging), a now by default enabled technic to speed up VM to host, or vice versa, switches.If you see a kernel log message containing KVM: entry failed, hardware error 0x80000021 you are affected.This has been adressed with the kernel package pve-kernel-5.15.39-3-pve with version 5.15.39-3 and newer, which is available on all repositories.
