После проблем с монтированием USB в stab070.2 - откатился на stab069.6 и жил на нем до сих под, пока не решил обновиться до зарелизенного сегодня stab070.12

Итак, что тут - что:
нода: 192.168.101.2
гейт: 192.168.101.11
ве-шки: 192.168.101.101 - 192.168.101.106
рабочий интерфейс: eth1

Грузимся с ядром 2.6.18-194.26.1.el5.028stab070.12

Видно, что таблица arp пустая, соединение наружу из VE (команда host) не проходит.

Ничего не меняем, перезагружаемся с ядром 2.6.18-194.3.1.el5.028stab069.6

cat /proc/net/arp нормальный, соединение наружу из VE работает.

Что делать? Smile
