- qemuxmlconftest: check various xml definitions of dataFileStore:
types file, block, network and the case when data-file belongs
to qcow2 backing image
- virstoragetest: create qcow2 image chains and check that data files
are properly probed by metadata parser
- qemuxmlactivetest: check that status files will contain data files'
node names
