It looks like the virtio-gpu flush should be fenced, but on the host side the received flush cmd doesn't have the fence flag set, and no fence_id. So, I have to reply right away instead of waiting for scanout to complete. Is that expected? then what's the
right way to vsync the guest?</div>

At the moment, I'm queueing up the resources for scanout, but guest is flushing faster than host vsync. I briefly looked at qemu implementation, but don't understand it yet. A high level breakdown of what should be happening would be extremely helpful!</div>
