[libvirt] [PATCH v2 5/5] RFC qemu: add spice opengl support

Marc-André Lureau marcandre.lureau at gmail.com
Wed Nov 25 08:42:34 UTC 2015


Add Spice graphics gl attribute. qemu 2.6 should have -spice gl=on
argument to enable opengl rendering context. This is necessary
to actually enable virgl rendering.

Add a qemuxml2argv test for virtio-gpu + spice with virgl.
