blockdev-snapshot-internal-sync
-------------------------------
Synchronously take an internal snapshot of a block device when the format of
image used supports it. If the name is an empty string, or a snapshot with
name already exists, the operation will fail.
Arguments:
- "device": device name to snapshot (json-string)
- "name": name of the new snapshot (json-string)
Example:
-> { "execute": "blockdev-snapshot-internal-sync",
"arguments": { "device": "ide-hd0",
"name": "snapshot0" }
}
<- { "return": {} }
