Intel Arc770 PCI Passthrough Troubles: BAR 2 Cant Reserve

[TheStig]

Greetings,

I have followed many tutorials on these forums as well as other resources and I cannot seem to get this to work. Right now the main issue is Bar 2 Cant Reserve. I think thats the main issue at least.

Host Specs:
CPU: 13700k
GPU: Arc 770
RAM: 32gb
Storage: ZFS/mirrored 480gb intel 3500's

VM:
Windows 11 Pro
8gb RAM (temporary)
12 "cores"

I have seen people post some commands so I will try to post some that I can remember, but please ask for whatever you need to help
