-block-commit
-------------
-
-Live commit of data from overlay image nodes into backing nodes - i.e., writes
-data between 'top' and 'base' into 'base'.
-
-Arguments:
-
-- "job-id": Identifier for the newly-created block job. If omitted,
-            the device name will be used. (json-string, optional)
-- "device": The device name or node-name of a root node (json-string)
-- "base": The file name of the backing image to write data into.
-          If not specified, this is the deepest backing image
-          (json-string, optional)
-- "top":  The file name of the backing image within the image chain,
-          which contains the topmost data to be committed down. If
-          not specified, this is the active layer. (json-string, optional)
-
-- backing-file:     The backing file string to write into the overlay
-                    image of 'top'.  If 'top' is the active layer,
-                    specifying a backing file string is an error. This
-                    filename is not validated.
-
-                    If a pathname string is such that it cannot be
-                    resolved by QEMU, that means that subsequent QMP or
-                    HMP commands must use node-names for the image in
-                    question, as filename lookup methods will fail.
-
-                    If not specified, QEMU will automatically determine
-                    the backing file string to use, or error out if
-                    there is no obvious choice. Care should be taken
-                    when specifying the string, to specify a valid
-                    filename or protocol.
-                    (json-string, optional) (Since 2.1)
-
-          If top == base, that is an error.
-          If top == active, the job will not be completed by itself,
-          user needs to complete the job with the block-job-complete
-          command after getting the ready event. (Since 2.0)
-
-          If the base image is smaller than top, then the base image
-          will be resized to be the same size as top.  If top is
-          smaller than the base image, the base will not be
-          truncated.  If you want the base image size to match the
-          size of the smaller top, you can safely truncate it
-          yourself once the commit operation successfully completes.
-          (json-string)
-- "speed":  the maximum speed, in bytes per second (json-int, optional)
-

-
--> { "execute": "block-commit", "arguments": { "device": "virtio0",
