This used to return 'unkown' and that was not correct. A vol-dumpxml now returns: <volume type='network'> <name>image3</name> <key>libvirt/image3</key> <source> </source> <capacity unit='bytes'>10737418240</capacity> <allocation unit='bytes'>10737418240</allocation> <target> <path>libvirt/image3</path> <format type='raw'/> </target> </volume> The RBD driver will now error out if a different format than RAW is provided when creating a volume.
