RE: [Xen-users] Multiple Bridges Fail to Start

Hi Tony!

Maybe not a solution to your problem, but it may help you to reach the
target:
I played around with that for days without getting it solved, so I left
that interface thing out of Xen. Means: Configure the Bridges and
Interfaces and all that acc. to your distro, e.g. ifcfg-xenbr0,
ifcfg-xenbr1, ifcfg-eth0, ... on Redhat (I can provide the infos, if you
need them).
Also just replace the network-script with a network-script-dummy, which
simply does nothing.

With that method I managed it to have VLANs on bonding interfaces
bridged into xenbr0 and xenbr1. 
But keep the names xenbr0 and xenbr1 - they are used too often somewhere
;-)

Subject: [Xen-users] Multiple Bridges Fail to Start

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:
