xen kernel и сабинтерфейсы

привет,

Есть CentOS 5.4, стандартный xen-kernel.

Все боле-менее работает. Но если я добавляю новый сабинтерфейс, например, eth0:1 с ip-адресом из другой подсети (мне это нужно для маршрутизации гостевых хостов), то после перезагрузки сервер становится недоступным по сети - даже не пингуется по eth0 и eth0:1 ip-адресам.

С чем это связано? Как проверить? Как вылечить?

Спасибо!

Да, пока машина грузится - несколько пингов проходят, потом прекращается.
