After a couple of seconds it comes back and as a confirmation I see this in its messages: Mar 8 17:38:57 T-ORACLE73 chronyd[616]: System clock wrong by 19.077230 seconds, adjustment started Is this expected? Possibly the default changed at some point in time, so that now it saves memory and so this implies pause of VM In the mean time I verified changing backup.py this way solves the problem (the 3.6 api deprecation still in place... ;-): $ diff backup.py backup.py.orig 123c123 < vm.snapshots.add(params.Snapshot(description=config.get_snapshot_description(), vm=vm,persist_memorystate=False)) --- > vm.snapshots.add(params.Snapshot(description=config.get_snapshot_description(), vm=vm)) The snapshot doesn't include memory and no problem at VM OS side now Tested also getting the parameter from config file Modifications needed in this case: 1) $ diff backup.py backup.py.orig 123c123 < vm.snapshots.add(params.Snapshot(description=config.get_snapshot_description(), vm=vm,persist_memorystate=config.get_persist_memorystate())) --- > vm.snapshots.add(params.Snapshot(description=config.get_snapshot_description(), vm=vm)) 2) $ diff config.py config.py.orig 34d33 < self.__persist_memorystate = config_parser.getboolean(section, "persist_memorystate") 113,116d111 < < < def get_persist_memorystate(self): < return self.__persist_memorystate And in config file called add: # Save Memory in snapshot persist_memorystate=False It could be further improved if one wants to differentiate save memory for some VMs and not for other ones.... HIH other ones, Gianluca
