Имеется гипервайзер, на котором нужно свести на одну машину трафик от всех машин. Я сделал следующее:
1. Соединил две машины при помоши openvswitch
2. Добавил интерфейсы с 8021q тегом
3. Настроил на одной машине vlan,ы
4. Добавил эти vlan'ы в сетевой мост
Проблема в том, что трафик между машинами ходить отказывается. Вот tcpdump с головной машины:
