In case of a single video card in the system, it would be wonderful to
be able to suddenly give the video card as passthrough to the guest
removing it from the host. Since the video card internal state is
unknown to the guest, the guest should then re-initialize it with some
help of a guest driver. For example it could act like resuming the
graphics from standby.
Giving the video card back to the host would need some kind of a hotkey.
While the video card is at the host, the guest graphics would be
invisible (not windowed). Alternatively the guest could be frozen.
Would that be anyhow feasible?
That would be just great for the people who use Windows for videogames
Thank you
Asdo
