# @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)
#
# @x-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 2.5)

#          migration, the decompression thread count is an integer between 1

#
# @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. This command is only
# supported on i386 and x86_64.
#
# @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
#
# @protocol: the filename or file descriptor of the vmcore. The supported
#            protocols are:

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

#          want to dump all guest's memory, please specify the start @begin
#          and @length
#
# @format: #optional if specified, the format of guest memory dump. But non-elf
#          format is conflict with paging and filter, ie. @paging, @begin and
