# Since: 1.1

{ 'command': 'guest-suspend-ram' }
##
# @guest-suspend-hybrid
#
# Save guest state to disk and suspend to ram.
#
# This command requires the pm-utils package to be installed in the guest.
#
# IMPORTANT: guest-suspend-hybrid requires QEMU to support the 'system_wakeup'
# command. Thus, it's *required* to query QEMU for the presence of the
# 'system_wakeup' command before issuing guest-suspend-hybrid.
#
# Returns: nothing on success
# If hybrid suspend is not supported, Unsupported
#
# Notes: o This is an asynchronous request. There's no guarantee a response
# will be sent
# o It's strongly recommended to issue the guest-sync command before
# sending commands when the guest resumes
#
# Since: 1.1
