I wish to make a bridge in my Dom0 that has no IP address assigned to it. By default, Xen attaches my peth0 interface to a bridge called eth0. I then have a firewall DomU with a network interface which is connected to the eth0 bridge. The problem is, is that the setup only works if eth0 in the Dom0 has an ip. If I do ifdown eth0 to remove the IP, the bridge stops working.
I believe the trick is to do "ip link up" (check man pages for correct syntax) to make the link itself active, but you don't need to add an IP.
