I wrote up 2 virtio-fb implementations a while back and I still believe it's a bad idea. Better implement QXL in kvm-tool, so work doesn't get needlessly duplicated. If you really have to use virtio for whatever reason (no PCI available), just write a small QXL over virtio transport that allows you to reuse the protocol. I really don't want to see people waste time on reinventing the wheel over and over again.
