Public bug reported:
I made simple Ubuntu 24.04 LTS Server installations as guests in an up-
to-date Proxmox. No Xorg/Wayland, just CLI! The virtual graphics card is
qml, 16 MiB memory (standard settings). Opening the console in the
Proxmox GUI, or via remote-viewer initially is fine. However, after some
time (usually: hours), the console just locks up. However, SSH into the
guest machine remains fine.
Ubuntu 22.04, or 20.04 are fine, the issue only occurs with the new
Ubuntu 24.04. The issue is reproducible with all Ubuntu 24.04 VMs. A
reboot the the VM makes the console usable again, until the issue occurs
again (usually after some hours).
Unusual observation from dmesg:
