Finally we have worked around this issue downgrading to kernel 5.13:

apt-get install proxmox-ve=7.1-1; apt-get remove pve-kernel-5.15.35-1-pve (+reboot)

No need to downgrade pve-qemu-kvm no qemu-server .

Sadly VMs running on kernel 5.15.35-1 will crash on live migration :-(


It is strange, as I don't see anybody saying they saw this problem on the forum :
https://forum.proxmox.com/threads/proxmox-ve-7-2-released.108970/page-3


I think Bengt Nolin in the first page is reporting something like this.

Also, I installed a few weeks ago the kernel 3.15.30-1 that was available for test on PVE 7.1, on my production servers, that solved for me another problem (windows VM not rebooting correctly), and I don't see the problem you encountered.

# uname -r
5.15.30-1-pve

I will test the upgrade shortly.

Our problem has been a headache in our tests today :) I asure you it is there, and it is fixed downgrading kernel.

I don't know why it's happening, but VMs' clock seems to broke suddenly and spectacularly... :)

Nodes have Ryzen CPUs, and storage is Ceph. Network is 10G for Ceph/migrations, 10G for VMs/cluster.

Cheers
