Graphics passthrough only works with a small selection of graphics cards, and requires latest upstream code. So if you're motivated you can get it to work but it isn't trivial.

Aside from that, ask on a spice specific list for more info. - Cole _______________________________________________ virt-tools-list mailing list virt-tools-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/virt-tools-list
