[Bug 470636] Re: virt-aa-helper fails to add copy-on-write images on apparmor profile

[Jamie Strandboge]

While this is technically different than 'kvm snapshot', this is
actually what I meant by 'snapshotting'. The problem is that there is
nothing in your XML that shows that there is a base image in use (or a
cow file for that matter). This is not expressed in your XML with the
backing store being managed outside of libvirt, and therefore cannot be
captured by the security driver.

The support that was added in 0.6.0 was for a backingstore when using a
storage volume (see
http://libvirt.org/formatstorage.html#StorageVolBacking). At this time,
the AppArmor security driver does not support a backing store, but will
in a future release. I'll update the bug accordingly.
