GPU passthrough to Linux VM not working


Go to solution Solved by Egon Olsen,

Hi,

In my server i have two GPUs, the primary is for unraid and then i have a nvida gtx 1070 for VMs.
The passthrough works perfect with my win11 VM but now i'm trying to passthrough the same GPU to a Linux VM just to try and learn.

I have tried different BIOS, i440fx, q35, i have tried a rom from techpowerup, i have tried to dump my own vbios..
whatever i test, the only thing i manage to get is a black screen, and sometimes my monitor doesn't even "wake up"...

 

I have rebooted the server between tries, i have successfully started my windows VM with passthorugh betweem tries.. but as soon as i start my new linux VM nothing happens.,

suggestions?

Try to setup your vm during installation with first GPU VNC and second your nvidia gtx 1070. Install your linux and vidia driver via VNC and when that is done, shutdown your vm, remove the vnc and set your nvidia gpu as the first one. That worked for me a while ago.

 

Never needed a bios file for my 970 and 1070.
