[CentOS-virt] Creating a new bridge with new eth

[dist-list at lexum.org]

Hello,
I am using eth0 as my xen management interface. There will no VM 
connected to the interface.
I read a lot of articule about adding a interface and create a new 
bridge. Some add a ip address to the new interface some don't.

Do I really need a IP on all interfaces ?

Tx
