+transaction
+-----------
+
+Atomically operate on one or more block devices. The only supported
+operation for now is snapshotting. If there is any failure performing
+any of the operations, all snapshots for the group are abandoned, and
+the original disks pre-snapshot attempt are used.
+
+A list of dictionaries is accepted, that contains the actions to be performed.
+For snapshots this is the device, the file to use for the new snapshot,
+and the format. The default format, if not specified, is qcow2.
+
+Each new snapshot defaults to being created by QEMU (wiping any
+contents if the file already exists), but it is also possible to reuse
+an externally-created file. In the latter case, you should ensure that
+the new image file has the same contents as the current one; QEMU cannot
+perform any meaningful check. Typically this is achieved by using the
+current image file as the backing file for the new image.
+
+Arguments:
+
+actions array:
+ - "type": the operation to perform. The only supported
+ value is "blockdev-snapshot-sync". (json-string)
+ - "data": a dictionary. The contents depend on the value
+ of "type". When "type" is "blockdev-snapshot-sync":
