Problem with VM - garbled novnc

[onepamopa]

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

Hi. I’m seeing the exact same issue and raised this yesterday (without a response as yet)... In my case changing the VM graphics adapter to SPICE works but I’d like to understand why the problem has started recently with the Default VGA adapter ...

as i wrote in the other topic, i believe this is a guest issue, specially with std vga and the ubuntu hwe kernel/xorg stack

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.
