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:

2357 May 31 16:57:04 zeus kernel: eth1: no IPv6 routers present

Thanks in advance,
