[Xen-users] bridged network without static ip

["Thoralf Schulze" <schulze@xxxxxxxxxxxxxxxxx>]

Hi there,

this is probably really lame, but i gotta ask anyways:

let's say that there is a machine (running debian lenny for both the dom0  
and the domUs) with two network interfaces running xen:
- eth0 should be for administrative purposes only: it has an ip from an  
internal network and allows logging in to the dom0 instance on the server
- eth1 is accessible from the outside and will be shared among some domUs,  
serving stuff to the internet
I'd like to set up networking in a way that all traffic on eth1 will never  
reach dom0. For this reason, the peth1 interface should not have a static  
ip - its traffic should merely travel across the eth1 network bridge to  
the domUs.
I tried to set up eth1 as

auto eth1
iface eth1 inet manual

in /etc/network/interfaces  - didn't work. apparently, eth1 isn't really  
up enough to get included in the bridge. In xend-config.sxp, there is a
(network-script 'network-bridge netdev=eth1')

entry, the domUs have

vif = [ 'ip=x.x.x.x.x,mac=w:h:a:t:ev:er,bridge=eth1' ]

statements in their configs.

It would be really great if someone could enlighten me on this ...

Thank you very much in advance,
thoralf.
