OS: Pop!_OS 21.04
Graphics Card: GTX 1660 Super

Note: I have followed the guide provided by Some Ordinary Gamers, but I also have used the guide provided by joeknock90. win10.log looks good to me, doesn't give errors.

Can anyone figure out what would be the problem?

Also, there are weird artifacts when booting the machine and booting the VM, on the splash screen there goes a line across the screen, it has multiple colors.

kvm.conf:

VIRSH_GPU_VIDEO=pci_0000_26_00_0
VIRSH_GPU_AUDIO=pci_0000_26_00_1
VIRSH_GPU_USB=pci_0000_26_00_2
VIRSH_GPU_SERIAL=pci_0000_26_00_3
