The apparmor profile from libvirt doesn't seem to work, only tearing down apparmor completely makes it tick. Getting that fixed for Ubuntu would be a big help.

If you need to test this, use virt-manager with a user session and try to use an existing bridge as the interface for a VM. You also need to create /etc/qemu/bridge.conf with a single line consisting of 'allow bridge0' depending on your interface name.

Will look into reporting the setuid bit not sticking to downstream but it's less of an issue than the apparmor profile as it prevents me from using apparmor right now.
