Depending on the pool type, this should be treated as file or block.
You do this correctly in patch 8, but I think it is not complete.  For
example, will your patches allow SCSI passthrough of a volume inside an
iSCSI pool?

Perhaps libvirt should always work in terms of enum virStorageVolType,
initializing it from either the pool or the "type" attribute.
