Hi,
I''ve configured dom0 sistem to use vlans. So I have
eth0, vlan2, vlan3
and bridges xenbr0, xenbr2, xenbr3
then I''ve configured domU to use xenbrX
Problem: everytime I boot domU I get different network interface in domU
Exampe:
- first boot - I have eth0 - nonworking and eth2 - working
- second boot of same machine - I get eth0 nonworking and eth4 - I can
configure it to work
- third boot of same machine - I get eth0 nonworking and eth5 - I can
configure it to work
I use SLES 10 SP1 on dom0 and domU.
I use /etc/xen/scripts/network-bridge to create xenbr0 and my script to
create other bridges
skript is called: create_bridge vlan_number
bridge="xenbr${bridge}"
vlan=$1
vlan="vlan${vlan}"
echo creating ${bridge}
brctl addbr ${bridge}
brctl stp ${bridge} off
brctl setfd ${bridge} 0
brctl addif ${bridge} ${vlan}
ip link set ${bridge} up
So my question is - how to configure network interfaces in domU to
automaticly bring up networking?
Thanks and bye

Hi, thanks - now i've seen my error - wrong configuration instead of vif=[ 'mac=00:16:3e:71:31:a2,bridge=xenbr3' ] I had vif=[ 'mac=00:16:3e:71:31:a2' , 'bridge=xenbr8' ] so I got two interfaces one with fixed mac but not working because it was not linked to bridge and one with everythime new mac addreess but linked to right address Thanks for suggestions bye 2007/9/14, Stefan Berner <Stefan.Berner@lrz-muenchen.de>:> > Hi Janko, > Janko Harej wrote: > > Hi, > > > > I've configured dom0 sistem to use vlans.
