+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": {} }
