WebGUI Console freezes on VM boot

[astro666]

Hi,

I have a strange one. I am running Ubuntu Server 24.04 on the latest release of Proxmox, freshly installed today. When I boot the VM and open the console (noVNC) it will run through the boot process but the session will 'freeze' at some point about halfway through the boot process. I can close the console window and reopen it, and it's still stuck at that spot. The window is non responsive and doesn't respond to any input.

SSHing into my server shows its booted and working fine, so it's like there is a specific issue or driver incompatibility for noVNC where the screen/KVM controller 'freezes' at that point in time.

I've tried default, standard VGA, VMWare compatible graphics card settings with no luck.Interestingly my VM wont successfully boot if I try and use the VirtIO-GPU option.

Ive accessed the console from Safari,and from chrome, with the same issue.

Any ideas?
Thanks

What about "qm terminal vmid" from the command line?

Output from the command line on the host:

Hello,
An update. I've found this 100% reproducible on new VMs of Ubuntu server 24.04. Even if there is a full PCI passthrough of the GPU (thus outputting VM display on external monitor) the vnc console still 'freezes' on the boot sequence. I have tried most display types (except virGL), with no luck.

To the question above, sorry I misunderstood. Output as follows (same behaviour on all ubuntu vms).
[CODE
root@proxmox-1:~# qm terminal 102 -iface serial0
starting serial terminal on interface serial0 (press Ctrl+O to exit)


[/CODE]
Nothing appears within the terminal, no login or anything. Rebooting the VM while connected to the serial shows the PVE boot sequence but not the VM boot sequence.

I have the exact same issue with ubuntu server console window freezing on boot when gpu passthrough. did you ever find a solution?

I'm having the same issue with Intel UHD 770 passthrough on an Ubuntu Server VM. Any luck getting it working?
