# Generates a snapshot of a block device.
#
+# 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.
+#
# For the arguments, see the documentation of BlockdevSnapshot.
#
# Since: 2.5
+#
+# Example:
+#
+# -> { "execute": "blockdev-add",
+# "arguments": { "options": { "driver": "qcow2",
+# "node-name": "node1534",
+# "file": { "driver": "file",
+# "filename": "hd1.qcow2" },
+# "backing": "" } } }
+#
+# <- { "return": {} }
+#
+# -> { "execute": "blockdev-snapshot",
+# "arguments": { "node": "ide-hd0",
+# "overlay": "node1534" } }
+# <- { "return": {} }
