Isn't the existing virtlockd support already sufficient for this? If
not, what is preventing the virtlock framework from interacting with rbd
disks?
Nothing really. The current impl only deals with disks with type=file
or type=block, ignoring type=network. We could extend it to cope with
the latter though - either using a URI to uniquely identify the network
storage, or better yet using some unique volume ID if available.
