So Working on CEntOS 5  I am trying to sett up Xen with 2 bridges, one that connects dom0 and most of the domU to the physical card and the out to the network.  Got that figured out no problem, now i want to have a second bridge that runs a local network for all the doms that doesn't connect to the network.

With code I have found used in multiple places I can easily get 2 bridges, and have all the Domu connected to it but i can't get Dom 0 to have an interface.

Script to set up bridges called fine from xend-config.sxp

]# cat multiple-bridge
#!/bin/sh
dir=$(dirname "$0")
"$dir/network-bridge" "$@" vifnum=0 netdev=eth0 bridge=xenbr0
"$dir/network-bridge" "$@" vifnum=2 netdev=dummy bridge=xenbrloc1


Out put from brctl show
