Do you mean Xen's network scripts? They are supposed to manage that, but 
have proven to do a not so great job. Mainly because of 
cross-distribution issues, as far as I know.
The general recommendation is to create the needed bridges by your 
distribution's means, and then tell Xen which bridge to use in what 
case. Very stable, very predictable, very flexible.
This threads might help to figure out how to set up the bridging networks:

For reference about Xen's networking model, I would recommend Xen's wiki:
http://wiki.xensource.com/xenwiki/XenNetworking (nicer pictures)
http://wiki.xen.org/wiki/Xen_Networking (more recent)

I can believe that. That is one fo the reasons for a recommendation to 
manage bridges somehow else, no via Xen's scripts.
In any case, definitely it's good idea to reboot your system as part of 
your normal pre-production tests, in order to make sure whatever 
configuration you have made is persistent.
While doing tests, the bridging setup is perfectly manageable on the 
fly. Sometimes, it VLANs and some buggy switch (hello, Trendnet) are 
involved, it's good idea to reset the network port.
