Теперь на стороне Open vSwitch:

# ovs-vsctl show

    Manager "tcp:10.10.10.20:6640"

    Bridge "vsw0"
        Controller "tcp:10.10.10.20:6653"
            is_connected: true

            Interface "vsw0"
                type: internal
    ovs_version: "2.9.0"

Контроллер переходит из ACTIVE в IDLE:

target              : "tcp:10.10.10.20:6653"

Логи показывают следующее.

Любые идеи, почему соединение OF не формируется?

Проблема заключалась в том, что мост не был настроен на протокол OpenFlow 1.3.

ovs-vsctl set bridge vsw0 protocols=OpenFlow13

Сразу после этого началась сессия:

Контроллер теперь «мастер»:
