The documentation states that for shallow block copy the image has to have the same guest visible content as backing file of the current image if the file is being reused. This condition can be achieved also with a raw file (or a qcow without a backing file) so remove the condition that would disallow it. (This patch additionally fixes crash described in https://bugzilla.redhat.com/show_bug.cgi?id=1215569 )
LibVirt : simple API for virtualization
Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.
