Putting together pieces from previous patches, it is now possible for 'virsh vol-dumpxml --pool gluster volname' to report metadata about a qcow2 file stored on gluster. The backing file is still treated as raw; to fix that, more patches are needed to make the storage backing chain analysis recursive rather than halting at a network protocol name, but that work will not need any further calls into libgfapi so much as just reusing this code, and that should be the only code outside of the storage driver that needs any help from libgfapi. Any additional use of libgfapi within libvirt should only be needed for implementing storage pool APIs such as volume creation or resizing, where backing chain analysis should be unaffected. * src/storage/storage_backend_gluster.c (virStorageBackendGlusterReadHeader): New helper function. (virStorageBackendGlusterRefreshVol): Probe non-raw files. 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.
