I got annoyed at having to use both 'virsh vol-list $pool --details' AND 'virsh vol-dumpxml $vol $pool' to learn if I had populated the volume correctly. Since two-thirds of the data present in virStorageVolGetInfo() already appears in virStorageVolGetXMLDesc(), this just adds the remaining piece of information, as:
<volume type='...'> ... </volume>
* docs/formatstorage.html.in: Document new <volume type=...>. * docs/schemas/storagevol.rng (vol): Add it to RelaxNG. * src/conf/storage_conf.h (virStorageVolTypeToString): Declare. * src/conf/storage_conf.c (virStorageVolTargetDefFormat): Output the metatype. (virStorageVolDefParseXML): Parse it, for unit tests. * tests/storagevolxml2xmlout/vol-*.xml: Update tests to match.

v1: https://www.redhat.com/archives/libvir-list/2013-November/msg00955.html Since then, delay 'network-dir' until later in gluster series, change XML to <volume type='file'> instead of <volume><type>file</type>, and use 1.2.0 instead of 1.1.5

You and Peter seem to be touching the same code in storage_conf.c: https://www.redhat.com/archives/libvir-list/2013-November/msg01030.html Although added virStorageVol was added in a different location... That'll make the 3 way merge interesting... Also, he seems to have also touched libvirt_private.syms too... John <...snip...>
