Hi!
I hope this is the proper mailing list. If not please tell me
where do I post my question. I have been attempting to create a setup
with a host debian (Lenny) system and currently two centos guest. I have
managed to get everything working except network communications between
my two guest. I can event login into the proper guest from my host. If
you need tcpdumps and/or arp results I can provide them. Thank you.
Here is my network configuration script.

brctl addbr br0
ifconfig br0 192.168.1.1 netmask 255.255.255.0 up
for i in `seq 0 $count`
do
j=$(($i+100));
tunctl -b -u uja -t tap$i
brctl addif br0 tap$i
ifconfig tap$i up 0.0.0.0 promisc

This is the commands I use to start my kvm instants.
macaddr=$(/sbin/ifconfig tap0 | grep HWaddr | awk -F ' ' '{print $5}')
kvm -name mds -no-acpi -hda $HOME/work/image1.img -net nic,macaddr=$macaddr
-net tap,ifname=tap0,script=no,downscript=no &
macaddr=$(/sbin/ifconfig tap1 | grep HWaddr | awk -F ' ' '{print $5}')
kvm -name oss -no-acpi -hda $HOME/work/image2.img -net nic,macaddr=$macaddr
-net tap,ifname=tap1,script=no,downscript=no &
