Hi,
I've got a problem with networking guest OS'es and can't seem to track
down the problem. I suspect it has something to do with not using eth0
on the host machine, rather I'm using eth1.
I have a server running RHEL 5.2 with 4 NIC ports on it. Only 1 port,
eth1 is active. I've modified the /etc/xen/xend-config.xsp to use eth1
using:
(network-script 'network-bridge netdev=eth1')
(vif-script vif-bridge)
I've created a few guest OSes (Linux and Windows) and can't get them to
see the network. One of the guest configurations has:
vif = [ "mac=00:16:3e:48:e3:bc,bridge=xenbr1" ]
If I run /sbin/ifconfig on the host machine, I see:

The guest OSs can't get a DHCP address. I tried disabling iptables on
the host OS thinking the firewall was blocking something, but that has
not effect.
I've done this before but using eth0. Is there anything else I need to
change that I'm missing?
