+Intel Arc A-Series GPUs VFIO passthrough no video out
+Description of problem:
+Once the VM is booted, the screen goes blank.
+Steps to reproduce:
+1. Passthough any Intel Arc A (Alchemist) series video card.
+2. Boot VM.
+3. Screen goes blank.
+Additional information:
+I have startup and shutdown scripts that detach and reattach the card and these scripts work fine if I test them alone. It's only when I start the VM that issue presents itself.
