I've observed a failing of AppArmor policy update with libvirt, qemu
and vagrant.
vagrant ask libvirt to create vmimage backing with other qcow2 image that
located in another directory.
virt-aa-helper should add it but fails.

running
sudo aa-complain /usr/lib/libvirt/virt-aa-helper
solves a problem. After running above command, I get following:

virt-aa-helper generates policy rule and reloaded properly.
The observation tell us a policy in
/etc/apparmor.d/usr.lib.libvirt.virt-aa-helper:
@{HOME}/** r,
/**.img r,
not working and fails update libvirt policy.
This behavior is same as #1236455.
