Looking Glass: Run a Windows VM on Linux in a Window with Native Performance

I use a separate GPU for my linux host and the windows VM.

I am 99.9% sure you can not passthru a GPU to a VM that is being used by the host.

edit: I think I misunderstood your question. The GPU that gets passed thru to the VM, never gets initialized by the host system during boot. So, if you want to change which GPU you want to passthru to the VM, you will have to reboot to allow your host to use the other GPU (and not init the on you want passed thru to the VM).

I would suggest you look at a youtube video where they run thru setting this up, so you get a better idea of what this entails!

Thanks! I'm still deciding if it's worth the effort just to play certain games on Windows 10. The ease with which I can change the OS-GPU association may be the deciding factor.
