When configuring a bridge ...
- The specification of "network" and "broadcast" may be safely omitted, ifupdown scripts do excellent job deducing this parameters. Omitting them leaves you less room to make a mistake.
- Consider adding "bridge_stp off" parameter. http://wiki.xen.org/wiki/Xen_Bridge_Loop#Why_STP_is_turned_off.3F
- Ensure the bridge ports (such as eth0 and 1) are not configured elsewhere.
