[KVM QEMU OVMF] RDP works, but GPU-Z shows 0MHz and 0MB VRAM

Hi!

I set up my VM folloing https://wiki.archlinux.org/index.php/PC … h_via_OVMF, and fixing up in some hiccups along the way I managed to set up my VM. However, when I start the VM headlessly from another computer, the screen goes from "loading initial intframs....." (The point where the GPU is cut off and connected to vfio-pci) to completely black.

I managed to RDP into the VM, where my NVIDIA 970m was immediately detected. I downloaded GeForce Experience and downloaded the latest driver. After I rebooted the same update showed up again, and this repeated three times before i stopped. I then downloaded GPU-Z and noticed the weird stuff.

It perfectly deteced my VBIOS and GPU model, but there was something strange. It said that I had a GPU clock speed of 0MHz and 0MB of VRAM. I think this might be conneced to why my screen only goes black.

Here is a picture of GPU-Z: https://i.imgur.com/WmmaaTM.png

There are no errors in "dmesg | grep -i vfio" exept for when I enable "rom bar" in the .xml file of the domain, then this shows up:

[ 162.988045] vfio-pci 0000:01:00.0: Invalid PCI ROM header signature: expecting 0xaa55, got 0xffff

Sorry for my bad English, I am Norweigan.

Thanks in advance!
