[Bug 470636] Re: AppArmor security driver does not support backingstore

[Jamie Strandboge]

Actually, it supports backing stores just fine in both Lucid and
Maverick (I use them all the time) for both storage pools and backed
qemu disks (I use them all the time) and the issue you are seeing is a
result of an upstream libvirt security fix, and not the AppArmor
security driver.

What changed in maverick is that libvirt 0.8.3 won't automatically probe
for the disk format (doing so causes various security problems), and
therefore the backing store, unless the disk format is specified in the
XML. Unfortunately this is not the case for virtinst, vmbuilder and any
home-brewed scripts when using non-raw disk formats (raw is the
default). See bug #656173 comment #7 for more details. I plan to fix
virtinst in an SRU (bug #655392) as well as vmbuilder.
