Im gonna cut right to the chase.
I had a windows gaming VM that was working awesome, until i took my graphics card out to put new thermal paste on and put it back in (Also modded the GPU with custom fans earlier). After this, at first the VM started being much more laggy and games were having "Out of memory" errors come up. Then the VM stopped working altogether. These are the errors i get from libvirtd:

Does anyone have an idea as to how i can fix this? Ive tried lots of different things but cant seem to figure it out. Like i said the VM was working great up until this. Really appreciate any help.

Figured it out. Some nvidia modules werent unloading so i had to use
systemctl stop nvidia-persistanced
in my start script.
