+ QEMU Monitor Protocol
+ =====================
+The QEMU Monitor Protocol (QMP) is a JSON[1] based protocol for QEMU.
+By using it applications can control QEMU in reliable and "parseable" way,
+QMP also provides asynchronous events support.
+For more information, please, refer to the following files:
+o qmp-spec.txt QEMU Monitor Protocol current draft 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 informations about the Virtal Machine
+To enable QMP, QEMU has to be started in "control mode". This is done
+by passing the flag "control" to the "-monitor" command-line option.
+For example:
+$ qemu [...] -monitor control,tcp:localhost:4444,server
+Will start QEMU in control mode, waiting for a client TCP connection
+on localhost port 4444.
+To manually test it you can connect with telnet and issue commands:
+$ telnet localhost 4444
+Trying ::1...
+Connected to localhost.
+Escape character is '^]'.
