VNC and GPU passthru with Linux VM

I'm having an hell of a time trying to get a Linux VM to work with a passed through GPU and VNC.

I know the passthrough works because I have it working in a Windows VM. I shut that VM down before fiddling with the Linux VM.

I can VNC to the Linux VM  with graphics set to VNC but then when I change the graphics to the Nvidia card, I can no longer access it. And when I change it back to VNC, I get a message that says the graphics has not initialized (yet) or "internal error: qemu unexpectedly closed the monitor: 2019-08-08T13:59:37.609434Z qemu-system-x86_64: -device pcie-pci-bridge,id=pci.8,bus=pci.2,addr=0x0: Bus 'pci.2' not found".

I'd expect to be able to access the VM when I put the graphics back to VNC.

I'm using MX Linux and X2Go.

Any ideas?

Right. I would use one or the other.

Are you saying that once you've made a choice to go the GPU route you can't go back to VNC?

You can use both one or the other but you need 2 separate VM templates.

Switching back and forth between them with the same template is doable but troublesome due potential errors in the template.


That is assuming your GPU resets itself correctly upon VM shutdown.

Hello Testdasi,


So you are saying that if I open create a VM with VNC and use the VM to install drives, nomachine, ect I cant change the graphics card to something else? I have to stay on VNC?


If thats the case then I have to create a VM from scratch using the gpu from the start?
