This sounds interesting. Know of any unusually good guides/resources for this?

I can't judge from the beginners standpoint, here are few places to start looking

https://nixos.org/wiki/QEMU_guest_with_VGA_passthrough

https://www.reddit.com/r/VFIO

I'd recommend going with NixOS and libvirt, but other communities such as around unRAID or Arch might be bigger.

Can you describe your current setup(HW/OS)?

i7-3770 (no K), ATI GPU, Gigabyte B75-D3V board. I boot into NixOS without X server and launch a Windows VM with libvirt using this config (redacted a bit).

snapshot=on option allows me to discard changes to the image with every launch, folders like Desktop, Downloads, etc are not part of the image.

When I do need to keep the changes I use a commit command, not mucking with actual snapshots anymore.

$ virsh qemu-monitor-command MAIN --hmp commit all

As for macOS VM, I haven't used one recently, but it's totally possible.
