Hi, I hope i posted this is the right section.
To keep this simple, I was previously on 6.11.1 and had a VM with my gpu passthrough working and decided to update after seeing Space invader's new video
after the update it bonked my VM and it wouldn't run.
I created a new VM with windows 10 install on it where it would run fine with the virtual display drivers but once I passthroug my GPU it doesn't want to start.
here is the xml for the vm
