operations
+# for now are drive-backup, internal and external snapshotting. A list of
+# dictionaries is accepted, that contains the actions to be performed.
+# If there is any failure performing any of the operations, all operations

+# For external snapshots, the dictionary contains the device, the file to use
for

+#
+# 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.
+#
+# On failure, the original disks pre-snapshot attempt will be used.
+#
+# For internal snapshots, the dictionary contains the device and the snapshot's
+# name. If an internal snapshot matching name already exists, the request will
+# be rejected. Only some image formats support it, for example, qcow2, rbd,
+# and sheepdog.
+#

-Atomically operate on one or more block devices. The only supported operations
-for now are drive-backup, internal and external snapshotting. A list of

-If there is any failure performing any of the operations, all operations
-for the group are abandoned.
-
-For external snapshots, the dictionary contains the device, the file to use for

-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.
-
-On failure, the original disks pre-snapshot attempt will be used.
-
-For internal snapshots, the dictionary contains the device and the snapshot's
-name. If an internal snapshot matching name already exists, the request will
-be rejected. Only some image formats support it, for example, qcow2, rbd,

-Notes:
-
-(1) The Human Monitor is NOT an stable interface, this means that command
- names, arguments and responses can change or be removed at ANY time.
- Applications that rely on long term stability guarantees should NOT
- use this command
-
-(2) Limitations:
-
- o This command is stateless, this means that commands that depend
- on state information (such as getfd) might not work
-
- o Commands that prompt the user for data (eg. 'cont' when the block
- device is encrypted) don't currently work
