inject-nmi
----------
-Inject an NMI on guest's CPUs.
+Inject an NMI on the default CPU (x86/s390) or all CPUs (ppc64).
Arguments: None.
<- { "return": {} }
Note: inject-nmi fails when the guest doesn't support injecting.
- Currently, only x86 (NMI) and s390x (RESTART) guests do.

+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

+@input-send-event
+-----------------
+
+Send input event to guest.
+
+Arguments:
+
+- "console": console index.
+- "events": list of input events.
+
+The consoles are visible in the qom tree, under
+/backend/console[$index]. They have a device link and head property, so
+it is possible to map which console belongs to which device and display.
+
+Example (1):
+
+Press left mouse button.
+
+-> { "execute": "input-send-event",
+ "arguments": { "console": 0,
+ "events": [ { "type": "btn",
+ "data" : { "down": true, "button": "Left" } } } }
+<- { "return": {} }

+-> { "execute": "input-send-event",
+ "arguments": { "console": 0,
+ "events": [ { "type": "btn",
+ "data" : { "down": false, "button": "Left" } } } }
+<- { "return": {} }
+
+Example (2):
+
+Press ctrl-alt-del.
+
+-> { "execute": "input-send-event",
+ "arguments": { "console": 0, "events": [
+ { "type": "key", "data" : { "down": true,
+ "key": {"type": "qcode", "data": "ctrl" } } },

+<- { "return": {} }
+
+Example (3):
+
+Move mouse pointer to absolute coordinates (20000, 400).
+
+-> { "execute": "input-send-event" ,
+ "arguments": { "console": 0, "events": [
+ { "type": "abs", "data" : { "axis": "X", "value" : 20000 } },
