VM with virtio timeout and rcu_preempt stalls unresponsive

[derjoerg]

Hi everybody,

I have on my proxmox several lxcs running, a windows-vm and a home-assistant vm. For several months everything worked like a charme and I'm totally happy with my setup. But since a few weeks I encounter on my home-assistant vm a strange behaviour. Every two to three days in the middle of the night (when also an internal backup of home-assistant is running) the vm becomes unresponsive and the only way to get it back to work is to completely restart the vm. In the console I see the following output when this happens:


I already installed intel-microcode, but with no change in behaviour.

Can anybody point me in the right direction?

Thanks a lot in advance
Joerg

Hi,
look at this thread similar type of crash relative to snapshot => https://forum.proxmox.com/threads/snapshot-causes-vm-to-become-unresponsive.153483/page-2
Be patient, I have similar crash too without snapshooting now on one of my debian12 VM with 8.2.5 and 6.8.12-2-pve, proxmox staff don't follow those reported crash, opened 27 August, staff answered 11 September and since no news .. we are 22 October and the thread still have crashes reports.
