  35# leading sentinel byte (0xFF) the client can check scan for.
  36#
  37# This is used by clients talking to the guest agent over the
  38# wire to ensure the stream is in sync and doesn't contain stale
  39# data from previous client. It must be issued upon initial
  40# connection, and after any client-side timeouts (including
  41# timeouts on receiving a response to this command).
  42#
  43# After issuing this request, all guest agent responses should be
  44# ignored until the response containing the unique integer value
  45# the client passed in is returned. Receival of the 0xFF sentinel
  46# byte must be handled as an indication that the client's
  47# lexer/tokenizer/parser state should be flushed/reset in
  48# preparation for reliably receiving the subsequent response. As
  49# an optimization, clients may opt to ignore all data until a
  50# sentinel value is receiving to avoid unnecessary processing of
  51# stale data.
  52#
  53# Similarly, clients should also precede this *request*
  54# with a 0xFF byte to make sure the guest agent flushes any
  55# partially read JSON data from a previous client connection.

  73# wire to ensure the stream is in sync and doesn't contain stale
  74# data from previous client. All guest agent responses should be
  75# ignored until the provided unique integer value is returned,
  76# and it is up to the client to handle stale whole or
  77# partially-delivered JSON text in such a way that this response
  78# can be obtained.
  79#
  80# In cases where a partial stale response was previously
  81# received by the client, this cannot always be done reliably.
  82# One particular scenario being if qemu-ga responses are fed
  83# character-by-character into a JSON parser. In these situations,
  84# using guest-sync-delimited may be optimal.
  85#
  86# For clients that fetch responses line by line and convert them
  87# to JSON objects, guest-sync should be sufficient, but note that
  88# in cases where the channel is dirty some attempts at parsing the
  89# response may result in a parser error.

 606# awaken, forcing the user to power cycle the guest to bring it back.

 610#   1. Wait for the SUSPEND QMP event from QEMU
