Not only kernel driver and qemu.  Right now neither qxl nor virtio-gpu
can communicate the actual layout back to the host.  So this also
requires changes to the guest/host protocol (i.e. the virtual hardware).

Do you have any feedback from mutter developers on the two approaches
(touchscreen-style autoconfig or x+y offsets)?
