Nor here. I can set up other bridges manual (see below)

OK, I will start with manual settings:

circus:/etc/xen/scripts# ./network start bridge=xen-br1 netdev=eth1
antispoof=yes
network start bridge=xen-br1 netdev=eth1 antispoof=yes
iptables: No chain/target/match by that name

in the domU I can see two NIC, but DHCP does not work. DomU domains
with static IPs work.

Now I have a bridge (xen-br1) using the mac address of eth1, however, when I do 
./network stop bridge=xen-br1 netdev=eth1 antispoof=yes
xen-br1 us still up. Is this normal?
