# @LostTickPolicy:
#
# Policy for handling lost ticks in timer devices.
#
# @discard: throw away the missed tick(s) and continue with future injection
#           normally.  Guest time may be delayed, unless the OS has explicit
#           handling of lost ticks
#
# @delay: continue to deliver ticks at the normal rate.  Guest time will be
#         delayed due to the late tick
#
# @merge: merge the missed tick(s) into one tick and inject.  Guest time
#         may be delayed, depending on how the OS reacts to the merging
#         of ticks
#
# @slew: deliver ticks at a higher rate to catch up with the missed tick. The
#        guest time should not be delayed once catchup is complete.

# @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)

#
# Migration parameters enumeration
#
# @compress-level: Set the compression level to be used in live migration,

#          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.
#
# @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)

#
# This command will cause the QEMU process to exit gracefully.  While every
# attempt is made to send the QMP response before terminating, this is not
# guaranteed.  When using this interface, a premature EOF would not be
# unexpected.
#

# Example:
#

#
# Stop all guest VCPU execution.
#
# Since:  0.14.0
#
# Notes:  This function will succeed even if the guest is already in the stopped
#         state.  In "inmigrate" state, it will ensure that the guest
#         remains paused once migration finishes, as if the -S option was
#         passed on the command line.

#
# Notes: A guest may or may not respond to this command.  This command
#        returning does not indicate that a guest has accepted the request or

#              not yet been set, DeviceEncrypted.
#
# Notes:  This command will succeed if the guest is currently running.  It
#         will also succeed if the guest is in the "inmigrate" state; in
#         this case, the effect of the command is to make sure the guest

# Returns: Nothing on success
#          If @name is not a valid network device, DeviceNotFound
#
# Since: 0.14.0
#
# Notes: Not all network adapters support setting link status.  This command
#        will succeed even if the network adapter does not support link status
#        notification.
#
# Example:
#
# -> { "execute": "set_link",
#      "arguments": { "name": "e1000.0", "up": false } }

#            kernel module cannot support it, KvmMissingCap
#          If no balloon device is present, DeviceNotActive
#
# Notes: This command just issues a request to the guest.  When it returns,
#        the balloon size may not have changed.  A guest can change the balloon
#        size independent of this command.
#
# Since: 0.14.0

##
# @transaction:
#
# Executes a number of transactionable QMP commands atomically. If any
# operation fails, then the entire set of actions will be abandoned and the
# appropriate error returned.
#
# For external snapshots, the dictionary contains the device, the file to use for
# the new snapshot, and the format.  The default format, if not specified, is
# qcow2.
#
# 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
# current image file as the backing file for the new image.
#
# On failure, the original disks pre-snapshot attempt will be used.
#
# For internal snapshots, the dictionary contains the device and the snapshot's
# name.  If an internal snapshot matching name already exists, the request will
# 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
# transaction.  When an I/O error occurs during deletion, the user needs to fix
# it later with qemu-img or other command.
#
# @actions: List of @TransactionAction;
#           information needed for the respective operations.
#
# @properties: #optional structure of additional options to control the
#              execution of the transaction. See @TransactionProperties
#              for additional detail.
#
# Returns: nothing on success
#
#          Errors depend on the operations of the transaction
#
# Note: The transaction aborts on the first failure.  Therefore, there will be
# information on only one failed operation returned in an error condition, and
# subsequent actions will not have been attempted.

# @qom-get:

# This command will get a property from a object model path and return the
# value.
#
# @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
#        indicate that the match was ambiguous.
#
# @property: The property name to read
#
# Returns: The property value.  The type depends on the property
#          type. child<> and link<> properties are returned as #str
#          pathnames.  All integer property types (u8, u16, etc) are
#          returned as #int.

##
# @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: #optional 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: #optional if specified, the starting physical address.

# 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.)
# * machine-type: CPU model may look different depending on the machine-type.
#   (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.
#
# Some architectures may not support baselining CPU models. s390x supports
# baselining CPU models.
#
# Returns: a CpuModelBaselineInfo. Returns an error if baselining CPU models is
#          not supported, if a model cannot be used, if a model contains
#          an unknown cpu definition name, unknown properties or properties
#          with wrong types.
