[SOLVED] GPU Passthrough VMs Starten nicht mehr

[Justin2266]

Ich habe diese Anleitung befolgt um GPU Passthrough mit einer GTX 760 zu machen. Diese hat dann ein Code 43 Error in Windows gezeigt. Nun habe ich es mit einer 1050 TI Probiert und diese hat ein Timeout. Was mache ich Falsch?

The Question is "solved". But how?

Sadly I have no clue, I needed to shutdown and restart the hole server then it worked. But I still have code 43 because of Nvidias drivers I think. My AMD RX 570 4GB worked flawlessly. As well my RX 6800 XT worked flawlessly without any configuration modifications like args -maschine or -cpu.
