As explained in cover it's from spice-common & spice-protocol (imho it's best to discuss the protocol first, but I got no feedback so far)
> Is there a patch set for spice-gtk and/or Qemu?
There is a wip qemu branch: https://github.com/elmarco/qemu/tree/virgl
and wip spice-gtk branch: https://github.com/elmarco/spice-gtk/tree/virgl
(I am waiting for protocol & server bits before sending those)
