[Xen-users] Xen Multiple Interface bridge creation fails

[Tony Angerame <aga1@xxxxxxxxxxxxxx>]

Hi,

I am using Xen 3.0.2 on SUSE SLES 10. I have created a script in 
/etc/xen/scripts called "network-mybridges" and use two lines to setup 
xenbr0 and xenbr1. When executed manually the script works fine and 
creates xenbr0 and xenbr1. I can then xm create -c <vmname>.
with absolutely no issues. It just won't work at boot time. It appears 
that the vif-bridge script is shutting down and deleting the devices 
(xenbr) at boot time instead of bringing them up. The script is 
configured into /etc/xen/xend-config.sxp.
Here is an excerpt from /var/log/messages:
