I don't think it's necessary, and it could easily be added later if needed. Ahem, scratch that. MonitorConfig isn't going to fly with virtio-gpu (at least not with multiple heads defined that way). With virtio_gpu we will have one display channel per head, so we can use the channel id to identify the scanout. > > qemu (with wip patches) can do that already, for non-qxl cards.

But does it make sense with the world moving forward to opengl/wayland? It will be obsolete in a few years ... cheers, Gerd _______________________________________________ Spice-devel mailing list Spice-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/spice-devel
