GPU passthrough on laptop with Quadro M1200 (code 43)

[sikander]

Hi.
I've set up my laptop as a proxmox server, and are trying to get GPU passthrough working.
The guest that I'm trying now is windows 10 pro, but I've had the same problem on linux (gpu won't work when I install drivers).

I've tried to figure out what the problem is for a couple of days now, and I guess it's because the drivers won't allow it when it discovers that it's in a hypervysor.
So if you guys have any ideas for things i could try, it would be highly appreciated!

I'm not sure if VE 6.3 can do it. I've been trying as well with no success but in my case the drivers do install and device manager shows the GPU with everything okay.

I don't really want to swap this node back to virt-manager but this breaks my use case for proxmox on this specific node.
