Don't use the backingStoreRaw as a indication of broken chains. Fill it always and tweak the broken image chain detector to avoid changing the semantics. The new semantics to detect a broken chain is the presence of string in backingStoreRaw but the lack of the backing chain metadata structure in the chain. Now that the raw backing store name is always filled there's no need to pass the raw name variable separately to fill in case the backing is not a file. Tweak the function so that it can handle a NULL in that case.
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.
