  10 # @qmp_capabilities:
  11 #
  12 # Enable QMP capabilities.
  13 #
  14 # Arguments:
  15 #
  16 # @enable: An optional list of QMPCapability values to enable.  The
  17 #     client must not enable any capability that is not mentioned in
  18 #     the QMP greeting message.  If the field is not provided, it
  19 #     means no QMP capabilities will be enabled.  (since 2.12)
  20 #
  21 # Example:
  22 #
  23 # -> { "execute": "qmp_capabilities",
  24 #      "arguments": { "enable": [ "oob" ] } }
  25 # <- { "return": {} }
  26 #
  27 # Notes: This command is valid exactly when first connecting: it must
  28 #     be issued before any other command will be accepted, and will
  29 #     fail once the monitor is accepting other commands.  (see qemu
  30 #     docs/interop/qmp-spec.rst)
  31 #
  32 #     The QMP client needs to explicitly enable QMP capabilities,
  33 #     otherwise all the QMP capabilities will be turned off by
  34 #     default.
