[New: openFATE 323357] seamless support for virgl/virtio-gpu on QEMU/KVM VMs using spice
Feature added by: Vasilis Liaskovitis (vliaskovitis) Feature #323357, revision 1 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: <graphics type='spice' /> to: <graphics type='sdl' display=':0' xauth='/home/user/.Xauthority'/> and add following command line args to qemu: <qemu:commandline> <qemu:arg value='-s'/> <qemu:arg value='-display'/> <qemu:arg value='gtk,gl=on'/> </qemu:commandline> 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 More info on virgl requirements and integration: https://www.kraxel.org/blog/tag/virtio-gpu/ https://www.kraxel.org/blog/tag/virgl/ 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 -- openSUSE Feature: https://features.opensuse.org/323357
