Any pre-requisite in laptop video adapter or other? You're hitting: https://bugzilla.redhat.com/show_bug.cgi?id=1337290 There's two pieces missing: 1) DAC access and 2) cgroup access, to the /dev/dri/render* file. All we have right now are workarounds: for #1 you can do: setfacl -m u:qemu:rw /dev/dri/renderD128 For the latter, the only option is to write a custom cgroup_device_acl in qemu.conf, which sucks for a number of reasons. Patches have been posted to fix this but they aren't applied yet: http://www.redhat.com/archives/libvir-list/2016-May/msg01435.html - Cole _______________________________________________ libvirt-users mailing list libvirt-users@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/libvirt-users
