Xen users - Nov 2007 - Xen 3.1.0 and openSuse 10.3 - xenbr0 won''t dissapear

Hello,
I use xen for a few months now and I upgraded to opensuse 10.3 with xen 
3.1 (64bit versions) recently.
Everything works fine, but there is a problem when I change 
xend-config.sxp to use my own network script (it''s slightly modified 
version of network-virtual scripts from 
http://en.opensuse.org/Xen3_yet_another_Virtual_Network_Concept ) 
instead of default network-bridge script. The problem is, that after 
restarting xend (and yes, I tried also a complete reboot of the whole 
system), there are not just my bridges xenbr1, xenbr2 and xenbr3, there 
is also a default xenbr0! I can remove it by "sh 
/etc/xen/scripts/network-bridge stop", but every time, when xend is 
restarted, it is there again. I use the same configuration like in 
previous version of xen, I doublechecked everything, I have even removed 
original network-bridge script, but the problem is still not solved.

Do you have any ideas, please?
I use the default configuration, the only change I made is one line in 
xend-config.sxp and adding my scripts to /etc/xen/scripts/ - and that 
scripts work fine, I tested them separately, they just create three 
bridges with IP addresses and add a few vlans to them.

Thank you,
Luke

Hallo!

Put your script instead of xend-config.sxp into a new init.d-script and
add it''s name to the line "Required-Start" in the file
/etc/init.d/xend
I have also set the "RUN_PARALLEL" in /etc/sysconfig/boot to no.
In xend-config.sxp you need to put a dummy network-bridge script ( only
a "exit 0" inside). Then you can have a complex network as you want!
With this modification''s my xen-network is always starting with all
elements, 2-3 ''normal'' bridges and 2-4 vnet''s with
peering between two
datacenters.. :-)

Thanks for an advice, it is a good idea and I tried it. But  it still 
didn''t solve my problem. It is the same like before, when xend starts, 
it creates an empty xenbr0 (just a bridge, with no interfaces on it and 
with no virtual interfaces like veth, peth or vif0.x). I tried to read 
all xen scripts related to bridging, but I didn''t find a single clue, 
why is xend doing it. It is like the program itself has somewhere stored 
a simple "brctl addbr xenbr0" command and executes it everytime it 
starts up.
