It's emitted when a VNC client session is activated by QEMU,
client's information such as port, IP and auth ID (if the
session is authenticated) are provided.
Event example:
{ "event": "VNC_INITIALIZED",

QEMU Monitor Protocol
=====================
Introduction
-------------
The QEMU Monitor Protocol (QMP) allows applications to communicate with
QEMU's Monitor.
QMP is JSON[1] based and has the following features:
- Lightweight, text-based, easy to parse data format
- Asynchronous events support
- Stability
For more information, please, refer to the following files:
o qmp-spec.txt QEMU Monitor Protocol current specification
o qmp-events.txt List of available asynchronous events
There are also two simple Python scripts available:
o qmp-shell A shell
o vm-info Show some information about the Virtual Machine
[1] http://www.json.org
Usage
-----
To enable QMP, QEMU has to be started in "control mode". There are
two ways of doing this, the simplest one is using the the '-qmp'
command-line option.
For example:
$ qemu [...] -qmp tcp:localhost:4444,server
Will start QEMU in control mode, waiting for a client TCP connection
on localhost port 4444.
It is also possible to use the '-mon' command-line option to have
more complex combinations. Please, refer to the QEMU's manpage for
more information.
Simple Testing
--------------
To manually test QMP one can connect with telnet and issue commands:
$ telnet localhost 4444
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
