Hello,

Suddenlty one of my VMs isn't working properly.
I get garbled output in novnc (attached image).

This happens on 2 separate computers (one of which had never opened pve web ui).

After few reboots the VM finally started working (at least - accepting ssh connections), however, the noVNC screen remains garbled.

Can someone help?

Regards,
O

The guest was working perfectly fine. No updates were installed on it prior to the problem.
So, I don't think this is a "guest" problem.

On all my tests regarding this issue, it was the described bug in this specific Ubuntu Kernel - to workaround, just use virtio or vmware as virtual grafic card.
