Or the inverse: virtualizing Windows on Linux. I used to do this for a while with a dedicated GPU, and, besides some minor glitches with audio which I didn’t get to solve, it worked very, very well.

(Why? Because I wanted to play some Windows-only games without having to reboot. Drivers were not a problem thanks to USB attaching in libvirt. That’s how I got to play Elite: Dangerous “in” Linux.)
