Intel GVT-g and KVM breaks Sway

Issues & Assistance Sway
1

I’m trying to use Intel GVT-g for a Windows 11 KVM guest.

I’m using a 10th gen intel processor, and I’m using tiny11 for the windows 11 iso.

I followed the arch wiki in order to set it up (Intel GVT-g - ArchWiki) .

I can create a new virtual GPU just fine but strange things happen when I spin up the WM. Once it spins up the host Sway desktop breaks. All windows dissapear, I can still see the i3status-rust waybar and the SWAY wallpaper but I can’t launch any gui apps with my sway shortcuts (I assume that they are starting in the background). The exception is nwg-bar whcih still starts.

I’m not sure if this is a fault with Sway or the KVM setup. I’ve added a bunch of kernel parameters in an effort to fix this (pcie_acs_override=downstream aiommu=pt kvm.ignore_msrs=1) part from the ones in the arch wiki.
The modules required seems to load alright and iommu seems to be active. Any ideas of what could be wrong would be appreciated. I’ve spent more time on this than I care to admit.
