Re: [libvirt-users] Need help using libvirt with qcow2 delta and base images
Jeremy,
Thank you so much for resolving my problem ;) The AppArmor configuration fix worked. I
am sure that you have saved me many more days of research. It looks like I have to
research this AppArmor business.
Thanks!

These indicate that AppArmor is denying access to the backing store, thus, your delta
image will not work.
You're going to need add a rule into /etc/apparmor.d/abstractions/libvirt-qemu so that
the backing store can be read. Something like:
/data/virtual/var/lib/libvirt/images/ubuntu910server64.qcow2 r,
or
/data/virtual/var/lib/libvirt/images/* r,
