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": { "driver": "qcow2",

                               "node-name": "node1534",

                               "file": { "driver": "file",

                                         "filename": "hd1.qcow2" },

                               "backing": "" } }
