[libvirt] [PATCH] qemu: add spice opengl support
Marc-André Lureau
marcandre.lureau at gmail.com
Thu Feb 18 16:39:08 UTC 2016
Add Spice graphics gl attribute. qemu 2.6 should have -spice gl=on argument to
enable opengl rendering context (patches on the ML). This is necessary to
actually enable virgl rendering.
Add a qemuxml2argv test for virtio-gpu + spice with virgl.
