                        QMP Supported Commands
                        ----------------------

This document describes all commands currently supported by QMP.

Most of the time their usage is exactly the same as in the user Monitor, this
means that any other document which also describe commands (the manpage,
QEMU's manual, etc) can and should be consulted.

QMP has two types of commands: regular and query commands. Regular commands
usually change the Virtual Machine's state someway, while query commands just
return information. The sections below are divided accordingly.

It's important to observe that all communication examples are formatted in
a reader-friendly way, so that they're easier to understand. However, in real
protocol usage, they're emitted as a single line.

Also, the following notation is used to denote data flow:

-> data issued by the Client
<- Server data response

Please, refer to the QMP specification (QMP/qmp-spec.txt) for detailed
information on the Server command and response formats.

NOTE: This document is temporary and will be replaced soon.

1. Regular Commands
===================

Server's responses in the examples below are always a success response, please
refer to the QMP specification for more details on error responses.

@table @var
@item count
is the number of items to be dumped.

@item format
can be x (hex), d (signed decimal), u (unsigned decimal), o (octal),
c (char) or i (asm instruction).

@item size
can be b (8 bits), h (16 bits), w (32 bits) or g (64 bits). On x86,
@code{h} or @code{w} can be specified with the @code{i} format to
respectively select 16 or 32 bit code instruction size.
