This patch is going to add SLIT table support in QEMU, and provides additional option `dist` for command `-numa` to allow user set vNUMA distance by QEMU command. With this patch, when a user wants to create a guest that contains several vNUMA nodes and also wants to set distance among those nodes, the QEMU command would like: ``` -numa node,nodeid=0,cpus=0 \ -numa node,nodeid=1,cpus=1 \ -numa node,nodeid=2,cpus=2 \ -numa node,nodeid=3,cpus=3 \ -numa dist,src=0,dst=1,val=21 \ -numa dist,src=0,dst=2,val=31 \ -numa dist,src=0,dst=3,val=41 \ -numa dist,src=1,dst=2,val=21 \ -numa dist,src=1,dst=3,val=31 \ -numa dist,src=2,dst=3,val=21 \ ``` Signed-off-by: He Chen <he.chen@linux.intel.com> Message-Id: <1493260558-20728-1-git-send-email-he.chen@linux.intel.com> Reviewed-by: Igor Mammedov <imammedo@redhat.com> Reviewed-by: Andrew Jones <drjones@redhat.com> Signed-off-by: Eduardo Habkost <ehabkost@redhat.com>

# = 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)
|
|

# @MigrationCapability:

# 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
|
|
#
|
|
# @rdma-pin-all: Controls whether or not the entire VM memory footprint is
|
|
# mlock()'d on demand or all at once. Refer to docs/rdma.txt for usage.
|
|
# Disabled by default. (since 2.0)
|
|
#
|
|
# @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)
|
|
#
|
|
# @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 )
|
|
#
|
|
# @events: generate events for each migration state change
|
|
# (since 2.4 )
|
|
#
|
|
# @auto-converge: If enabled, QEMU will automatically throttle down the guest
|
|
# to speed up convergence of RAM migration. (since 1.6)
|
|
#
|
|
# @postcopy-ram: Start executing on the migration target before all of RAM has
|
|
# been migrated, pulling the remaining pages along as needed. NOTE: If
|
|
# the migration fails during postcopy the VM will fail. (since 2.6)
|
|
#
|
|
# @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)
|
|
#
|
|
# @release-ram: if enabled, qemu will free the migrated ram pages on the source
|
|
# during postcopy-ram migration. (since 2.9)

# Since: 1.2

#
|
|
# Each new snapshot defaults to being created by QEMU (wiping any
|
|
# contents if the file already exists), but it is also possible to reuse
|
|
# an externally-created file. In the latter case, you should ensure that
|
|
# the new image file has the same contents as the current one; QEMU cannot

# perform any meaningful check. Typically this is achieved by using the

# For internal snapshots, the dictionary contains the device and the snapshot's

# be rejected. Only some image formats support it, for example, qcow2, rbd,
|
|
# and sheepdog.
|
|
#
|
|
# On failure, qemu will try delete the newly created internal snapshot in the

# @path: The path within the object model. There are two forms of supported

# paths--absolute and partial paths.
|
|
#
|
|
# Absolute paths are derived from the root object and can follow child<>
|
|
# 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
|
|
# designed to make specifying objects easy. At each level of the
|
|
# 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

# Returns: The property value. The type depends on the property

# @dump-guest-memory:
|
|
#
|
|
# Dump guest's memory to vmcore. It is a synchronous operation that can take
|
|
# very long depending on the amount of guest memory.
|
|
#
|
|
# @paging: if true, do paging to get guest's memory mapping. This allows
|
|
# using gdb to process the core file.
|
|
#
|
|
# 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
|
|
# 3. Currently only supported on i386 and x86_64.
|
|
#
|
|
# @protocol: the filename or file descriptor of the vmcore. The supported
|
|
# protocols are:
|
|
#
|
|
# 1. file: the protocol starts with "file:", and the following
|
|
# string is the file's path.
|
|
# 2. fd: the protocol starts with "fd:", and the following string
|
|
# is the fd's name.
|
|
#
|
|
# @detach: if true, QMP will return immediately rather than
|
|
# waiting for the dump to finish. The user can track progress
|
|
# using "query-dump". (since 2.6).
|
|
#
|
|
# @begin: if specified, the starting physical address.
|
|
#
|
|
# @length: if specified, the memory size, in bytes. If you don't
|
|
# want to dump all guest's memory, please specify the start @begin
|
|
# and @length
|
|
#
|
|
# @format: if specified, the format of guest memory dump. But non-elf
|
|
# format is conflict with paging and filter, ie. @paging, @begin and
|
|
# @length is not allowed to be specified with non-elf @format at the
