# @stop:
#
# Stop all guest VCPU execution.
#
# Since:  0.14.0
#
# Notes:  This function will succeed even if the guest is already in the stopped
1506 1507 1508
#         state.  In "inmigrate" state, it will ensure that the guest
#         remains paused once migration finishes, as if the -S option was
#         passed on the command line.
