Title: seamless support for virgl/virtio-gpu on QEMU/KVM VMs using
spice
Requested by: Vasilis Liaskovitis (vliaskovitis)
Partner organization: openSUSE.org
Description:
- virgl/virtio-gpu for qemu/KVM support exists since qemu 2.6 Guest
- requirements are met by openSUSE Tumbleweed: guest kernel >= 4.4, mesa
- >= 11.1, xorg server >= 1.19 However the following host requirement is
- not met in TW/Factory: spice server >= 0.13.2 Current libspice-server1
- package is 0.12.8 in TW/Factory. The current workaround is to not use
- spice but to use sdl/gtk with virtio-gpu/virgl instead, and is quite
- messy: - libvirt VM definition needs to change: to: <graphics type='sdl' display=':0' xauth='/home/user/.
- Xauthority'/> and add following command line args to qemu: Also user's X display needs
- to be shared with qemu user/group: xhost +SI:localgroup:qemu Note: For
- complete virgl integration, there are also some missing pieces from
- libvirt (regarding cgroup permissions), which are not accepted in
- upstream libvirt afaik (at least not yet), see: https://www.redhat.com/archives/libvirt-users/2016-December/msg00014.html

Business case (Partner benefit):
openSUSE.org: This would allow: - Seamless and easy usage of virtio-gpu
/ virgl driver in qemu/KVM openSUSE VMs. - Development of new virtio-
gpu driver features on openSUSE (e.g. next step for virgl/virtio-gpu is
to support vulkan API), performance comparisons b/w virgl and llvmpipe
mesa drivers
