Comment 14 for bug 656173

I can see already a Problem with the opennebula package.
It will no longer work, since it does not generate this information on the domain xmls - it would not have this information anyway - else if it would probe for the data type of the image, this - we are being told - being a security issue.
@Jamie: I think the OS *in the guest* should never ever have access to the file of the image!
It should only have access to the virtualized disks, not to the file itself, where the backingstore informations are.
If it is now so, then the issue is rooted in qemu/kvm and not in libvirt.
