Public bug reported:
Updated my machine to questing. KVM virtual machines that use VirGL for
GPU acceleration are no longer booting.
The journal shows apparmor denials in accessing GPU sysfs entries before
qemu-system-x86 segfaults.
Disabling virtio 3d acceleration in the libvirt config makes the VMs
boot again.
