# = Other events
##

##
# @SHUTDOWN:
#
# Emitted when the virtual machine has shut down, indicating that qemu is
# about to exit.
#
# @guest: If true, the shutdown was triggered by a guest request (such as
# a guest-initiated ACPI shutdown request or other hardware-specific action)
# rather than a host request (such as sending qemu a SIGINT). (since 2.10)
#
# Note: If the command-line option "-no-shutdown" has been specified, qemu will
# not exit, and a STOP event will eventually follow the SHUTDOWN event
#
# Since: 0.12.0
#
# Example:
#
# <- { "event": "SHUTDOWN", "data": { "guest": true },
#      "timestamp": { "seconds": 1267040730, "microseconds": 682951 } }
#
##
{ 'event': 'SHUTDOWN', 'data': { 'guest': 'bool' } }

##
# @POWERDOWN:
#
# Emitted when the virtual machine is powered down through the power control
# system, such as via ACPI.
#
# Since: 0.12.0
#
# Example:
#
# <- { "event": "POWERDOWN",
#      "timestamp": { "seconds": 1267040730, "microseconds": 682951 } }
#
##
{ 'event': 'POWERDOWN' }

##
# @RESET:
#
# Emitted when the virtual machine is reset
#
# @guest: If true, the reset was triggered by a guest request (such as
# a guest-initiated ACPI reboot request or other hardware-specific action)
# rather than a host request (such as the QMP command system_reset).
# (since 2.10)
#
# Since: 0.12.0
#
# Example:
#
# <- { "event": "RESET", "data": { "guest": false },

##
# @SUSPEND_DISK:
#
# Emitted when guest enters a hardware suspension state with data saved on
# disk, for example, S4 state, which is sometimes called hibernate state
#
# Note: QEMU shuts down (similar to event @SHUTDOWN) when entering this state
#
# Since: 1.2
#
# Example:
