Why would you dedicate a physical interface to something that that isn't 
doing any real physical (sending something over a wire outside of the 
virtual world) work?  You don't need a physical interface for a bridge. 
  Just create an ifcfg-br123 or whatever.  If you don't plan on using 
eth1 for anything, maybe create bond0 with eth0 and eth1 for some 
redundancy.
