+# @inmigrate: guest is paused waiting for an incoming migration. Note
+# that this state does not tell whether the machine will start at the
+# end of the migration. This depends on the command-line -S option and
+# any invocation of 'stop' or 'cont' that has happened since QEMU was
+# started.
#
# @internal-error: An internal error that prevents further guest execution
# has occurred
# Since: 0.14.0
#
# Notes: This function will succeed even if the guest is already in the stopped
-# state
+# 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.
