| 13:51:37 | ignaziocassano | Sean, I desabled the workaround for using legacy port binding. I think It is automatically disabled when I upgraded from stein to train because workaround.py is covered be new version. Right ? | |

| 14:01:49 | ignaziocassano | OK. Let me to recap: 1) check if patch is includes. If not I patch code with patch command. 2) enable live_migration_events=true | |
