+change-backing-file
+-------------------
+Since: 2.1
+
+Change the backing file in the image file metadata. This does not cause
+QEMU to reopen the image file to reparse the backing filename (it may,
+however, perform a reopen to change permissions from r/o -> r/w -> r/o,
+if needed). The new backing file string is written into the image file
+metadata, and the QEMU internal strings are updated.
+
+Arguments:
+
+- "image-node-name": The name of the block driver state node of the
+ image to modify. The "device" is argument is used to
+ verify "image-node-name" is in the chain described by
+ "device".
+ (json-string, optional)
+
+- "device": The name of the device.
+ (json-string)
+
+- "backing-file": The string to write as the backing file. This string is
+ not validated, so care should be taken when specifying
+ the string or the image chain may not be able to be
+ reopened again.
+ (json-string)
+
+Returns: Nothing on success
+ If "device" does not exist or cannot be determined, DeviceNotFound
