Привет, коллеги.

Надо ли в dom0 прописывать бридж в /etc/network/interfaces ?

А то у меня вроде и так работает...

И каково-же содержимое /etc/xen/xend-config.sxp в строках:
(network-script
(vif-script

?

Вообще можно конечно и без бриджа - если настраивать dom0 как роутер.
Хотя может я и не прав.....
