[7.0.0-beta.2] VM XML error after switching to GPU passthrough and back to virtual.

I played a bit around with VM and GPU passthrough. When I try to switch back to virtuaI get this error:

I had choosen AMD Raphael before and when I start the VM the whole host GUI was unresponsive so I had to do a hard reboot, because "reboot" via cmd didn't work as well (stucks at unmounting drives). I think that should never happen...

Can was made to fix an issue of changing from a GPU back to virtual. This sets video to use these pci settings.
You seem to have a lot of pci controllers in the xml. Do other VMs have as many?
Could you post diagnostics?
