One further thing we should discuss is the block copy job, where we

interface which we need to figure out too sooner or later.
For that interface, I wonder if the best approach is to add a new flag.
By default, when the flag is 0, the new disk string is treated as a
path name in the local file system. But when the flag is set, the new
disk string is treated as an XML document describing the full <disk>
details, which gives us the full flexibility for a volume within a
storage pool or the full details of a network device such as gluster, or
even a network device that has multiple <host> subelements.
