I was under the impression that libvirt chmods/chowns all disks so they
are accessible by QEMU. Is this a bug in libvirt because the owner is
only changed for the overlay but not for all the backing files?

Or is libvirt just being sloppy in the job and it only changes the owner
of the file but does not check the path if there is any permission
problem along the way on some directory? (Although I'm not sure what
would be a proper response from libvirt in this case.)
