[PVE-User] PVE 7.2 unstability

[Eneko Lacunza]

Hi,

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 :-(

Cheers
