So far, my work has been merely preserving the status quo of backing file analysis. But this patch starts to tread in the territory of making the backing chain code more powerful - we will eventually support network storage containing non-raw formats. Here, we expose metadata information about a network backing store, even if that information is still hardcoded to a raw format for now. * src/util/virstoragefile.c (virStorageFileGetMetadataRecurse): Also populate struct for non-file backing. (virStorageFileGetMetadata, virStorageFileGetMetadatainternal): Recognize non-file top image. (virFindBackingFile): Add comment. (virStorageFileChainGetBroken): Adjust comment, ensure output is set. * tests/virstoragetest.c (mymain): Update test to reflect it. Signed-off-by: Eric Blake <eblake@redhat.com>
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.
