Laurent Vivier a5ebce3857 qmp: add QMP command x-query-virtio
This new command lists all the instances of VirtIODevices with
their canonical QOM path and name.

[Jonah: @virtio_list duplicates information that already exists in
 the QOM composition tree. However, extracting necessary information
 from this tree seems to be a bit convoluted.

 Instead, we still create our own list of realized virtio devices
 but use @qmp_qom_get with the device's canonical QOM path to confirm
 that the device exists and is realized. If the device exists but
 is actually not realized, then we remove it from our list (for
 synchronicity to the QOM composition tree).

 Also, the QMP command @x-query-virtio is redundant as @qom-list
 and @qom-get are sufficient to search '/machine/' for realized
 virtio devices. However, @x-query-virtio is much more convenient
 in listing realized virtio devices.]

# = Introduction
#
# 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:
#
# Example:
#
# ::
#
# -> data issued by the Client
# <- Server data response
#
# Please, refer to the QMP specification (docs/interop/qmp-spec.txt) for
# detailed information on the Server command and response formats.
#
# = Stability Considerations
#
# The current QMP command set (described in this file) may be useful for a
# number of use cases, however it's limited and several commands have bad
# defined semantics, specially with regard to command completion.
#
# These problems are going to be solved incrementally in the next QEMU releases
# and we're going to establish a deprecation policy for badly defined commands.
#
# If you're planning to adopt QMP, please observe the following:
#
# 1. The deprecation policy will take effect and be documented soon, please
# check the documentation of each used command as soon as a new release of
# QEMU is available
#
# 2. DO NOT rely on anything which is not explicit documented
#
# 3. Errors, in special, are not documented. Applications should NOT check
# for specific errors classes or data (it's strongly recommended to only
# check for the "error" key)
#
##
{ 'include': 'pragma.json' }
# Documentation generated with qapi-gen.py is in source order, with
# included sub-schemas inserted at the first include directive
# (subsequent include directives have no effect). To get a sane and
# stable order, it's best to include each sub-schema just once, or
# include it first right here.
