An outgoing non-blocking connection is triggered by tcp_start_outgoing_migration, once the connection is completed the tcp_wait_for_connect() callback is executed by the main loop. > nonblocking) function).

Within that callback there's a call to migrate_fd_connect(), which is where the migration thread is created. Incoming migration is still handled by the main loop's thread > Thanks! > Yaodong > -- > Yaodong Yang > Computer Science and Engineering Department > University of Nebraska--Lincoln, > Lincoln, NE, U.S.A.
