Bridge not coming up

Bridge not coming up

[Phil Carinhas]

  
    For some reason, Xend wont start the bridge on boot.
All the vif's are up for 3 domains, but no bridge.
The configuration file xend-config.sxp clearly has (vif-bridge xen-br0)
If I restart xend, the bridge comes up and all works ok.
This is an SMP machine RHEL3. I usually set cpu=-1. Thanks,

Have you checked the files /var/log/{xend,xend-debug}.log?  Do they contain 
evidence of any interesting explosions?  If so, please post it back to us.

Does anyone else with RHEL see this?

 Here is the tail end of a boot sequence where this happend..
Simply doing a 'xend restart' seems to fix the problem.

  RHEL put brctl in /usr/local/sbin where none of the scripts could find
 it.. Made a smylink to /sbin ...

 Now the br0 comes up at boot fine: but I can't make network connection
 to any domain until the domain first talks through the bridge. 
 This is true if you ping out to the net or to a neighboring domain.
