Do you still have network connectivity in dom0 after starting xend?
Please post the output of the following commands before and after
starting xend:
ifconfig
brctl show
I see your setup has an eth1. Does it also have an eth0? Which do you
want on xen-br0? Have you edited the default netdev line at the top of
the new network script?
Thanks,
Ian
