charset="utf-8" From: Juraj Marcin When exit-on-error was added to migration, it wasn't added to postcopy. Even though postcopy migration will usually pause and not fail, in cases it does unrecoverably fail before destination side has been started, exit-on-error will allow management to query the error.
