# = 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/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)

# Migration capabilities enumeration
#
# @xbzrle: Migration supports xbzrle (Xor Based Zero Run Length Encoding).
#          This feature allows us to minimize migration traffic for certain work
#          loads, by sending compressed difference of the pages
#
861
# @rdma-pin-all: Controls whether or not the entire VM memory footprint is
862
#          mlock()'d on demand or all at once. Refer to docs/rdma.txt for usage.
863
#          Disabled by default. (since 2.0)
864
#
865 866 867 868 869 870
# @zero-blocks: During storage migration encode blocks of zeroes efficiently. This
#          essentially saves 1MB of zeroes per block on the wire. Enabling requires
#          source and target VM to support this feature. To enable it is sufficient
#          to enable the capability on the source VM. The feature is disabled by
#          default. (since 1.6)
#
871 872 873 874 875 876 877 878
# @compress: Use multiple compression threads to accelerate live migration.
#          This feature can help to reduce the migration traffic, by sending
#          compressed pages. Please note that if compress and xbzrle are both
#          on, compress only takes effect in the ram bulk stage, after that,
#          it will be disabled and only xbzrle takes effect, this can help to
#          minimize migration traffic. The feature is disabled by default.
#          (since 2.4 )
#
879 880 881
# @events: generate events for each migration state change
#          (since 2.4 )
#
882 883 884

#          to speed up convergence of RAM migration. (since 1.6)
#
D
Dr. David Alan Gilbert 已提交
885
# @postcopy-ram: Start executing on the migration target before all of RAM has

#          been migrated, pulling the remaining pages along as needed. NOTE: If
D

#          the migration fails during postcopy the VM will fail.  (since 2.6)
888
#
889 890 891 892 893
# @x-colo: If enabled, migration will never end, and the state of the VM on the
#        primary side will be migrated continuously to the VM on secondary
#        side, this process is called COarse-Grain LOck Stepping (COLO) for
#        Non-stop Service. (since 2.8)

# Migration parameters enumeration
#
# @compress-level: Set the compression level to be used in live migration,
#          the compression level is an integer between 0 and 9, where 0 means
#          no compression, 1 means the best compression speed, and 9 means best
#          compression ratio which will consume more CPU.
#
# @compress-threads: Set compression thread count to be used in live migration,
#          the compression thread count is an integer between 1 and 255.
#
# @decompress-threads: Set decompression thread count to be used in live
#          migration, the decompression thread count is an integer between 1
#          and 255. Usually, decompression is at least 4 times as fast as
#          compression, so set the decompress-threads to the number about 1/4
#          of compress-threads is adequate.
#
980 981 982
# @cpu-throttle-initial: Initial percentage of time guest cpus are throttled
#                        when migration auto-converge is activated. The
#                        default value is 20. (Since 2.7)
983
#
984 985 986

# @tls-creds: ID of the 'tls-creds' object that provides credentials for
#             establishing a TLS connection over the migration data channel.
#             On the outgoing side of the migration, the credentials must
#             be for a 'client' endpoint, while for the incoming side the
#             credentials must be for a 'server' endpoint. Setting this
#             will enable TLS for all migrations. The default is unset,
#             resulting in unsecured migration at the QEMU level. (Since 2.7)
#
# @tls-hostname: hostname of the target host for the migration. This is
#                required when using x509 based TLS credentials and the

1001
#                certificate identity can be validated. (Since 2.7)

# @path: The path within the object model.  There are two forms of supported
2849 2850
#        paths--absolute and partial paths.
#
2851
#        Absolute paths are derived from the root object and can follow child<>
2852 2853 2854 2855 2856 2857
#        or link<> properties.  Since they can follow link<> properties, they
#        can be arbitrarily long.  Absolute paths look like absolute filenames
#        and are prefixed  with a leading slash.
#
#        Partial paths look like relative filenames.  They do not begin
#        with a prefix.  The matching rules for partial paths are subtle but
2858
#        designed to make specifying objects easy.  At each level of the
2859 2860 2861 2862 2863 2864 2865 2866
#        composition tree, the partial path is matched as an absolute path.
#        The first match is not returned.  At least two matches are searched
#        for.  A successful result is only returned if only one match is
#        found.  If more than one match is found, a flag is return to
#        indicate that the match was ambiguous.
#
# @property: The property name to read
#
2867 2868 2869 2870

#
# Notes:
#
# 1. It's a bad idea to use a string for the uri, but it needs to stay
#    compatible with -incoming and the format of the uri is already exposed
#    above libvirt.
#
# 2. QEMU must be started with -incoming defer to allow migrate-incoming to
#    be used.
#
# 3. The uri format is the same as for -incoming
#
# Example:
#
# -> { "execute": "migrate-incoming",
#      "arguments": { "uri": "tcp::4446" } }
# <- { "return": {} }

# @dump-guest-memory:
3292 3293
#
# Dump guest's memory to vmcore. It is a synchronous operation that can take
3294
# very long depending on the amount of guest memory.
3295 3296

# @paging: if true, do paging to get guest's memory mapping. This allows

#          IMPORTANT: this option can make QEMU allocate several gigabytes
#                     of RAM. This can happen for a large guest, or a
#                     malicious guest pretending to be large.
#
#          Also, paging=true has the following limitations:
#
#             1. The guest may be in a catastrophic state or can have corrupted
#                memory, which cannot be trusted
#             2. The guest can be in real-mode even if paging is enabled. For
#                example, the guest uses ACPI to sleep, and ACPI sleep state
#                goes in real-mode
3310

# @query-cpu-model-baseline:
#
# Baseline two CPU models, creating a compatible third model. The created
# model will always be a static, migration-safe CPU model (see "static"
# CPU model expansion for details).
#
# This interface can be used by tooling to create a compatible CPU model out
# two CPU models. The created CPU model will be identical to or a subset of
# both CPU models when comparing them. Therefore, the created CPU model is
# guaranteed to run where the given CPU models run.
#
# The result returned by this command may be affected by:
#
# * QEMU version: CPU models may look different depending on the QEMU version.
#   (Except for CPU models reported as "static" in query-cpu-definitions.)
4531
# * machine-type: CPU model may look different depending on the machine-type.
4532 4533 4534 4535 4536 4537 4538 4539
#   (Except for CPU models reported as "static" in query-cpu-definitions.)
# * machine options (including accelerator): in some architectures, CPU models
#   may look different depending on machine and accelerator options. (Except for
#   CPU models reported as "static" in query-cpu-definitions.)
# * "-cpu" arguments and global properties: arguments to the -cpu option and
#   global properties may affect expansion of CPU models. Using
#   query-cpu-model-expansion while using these is not advised.
#
4540 4541
# Some architectures may not support baselining CPU models. s390x supports
# baselining CPU models.
