+blockdev-snapshot
+-----------------
+Since 2.5
+
+Create a snapshot, by installing 'node' as the backing image of
+'overlay'. Additionally, if 'node' is associated with a block
+device, the block device changes to using 'overlay' as its new active
+image.
+
+Arguments:
+
+- "node": device that will have a snapshot created (json-string)
+- "overlay": device that will have 'node' as its backing image (json-string)
+
+Example:
+
+-> { "execute": "blockdev-add",
+ "arguments": { "options": { "driver": "qcow2",
+ "node-name": "node1534",
+ "file": { "driver": "file",

+ "backing": "" } } }
