Xen users - Nov 2006 - Problem setting up LVS (Linux Virtual Server) in Xen Virtual Machine

Hi all,

I''m trying to setup 3 virtual machines, 1 with LVS (Linux Virtual 
Server) load-balancing and 2 with Tomcat+Axis (webserver and stuff).

I''m using openSUSE 10.1 (xen 3.0.2) in all VMs and Dom0. rcSuseFirewall
is stopped, iptables -l report everything "accept"''ing.

Here''s my IP configuration:
http://pwp.netcabo.pt/pformoso/network.gif

You can see there are 3VMs running.


In the LB virtual machine I configure Linux Virtual Server (ipvsadm):
ipvsadm -A -t 192.168.200.180:8080 -s rr
ipvsadm -a -t 192.168.200.180:8080 -r 192.168.200.185:8080 -m
ipvsadm -a -t 192.168.200.180:8080 -r 192.168.200.190:8080 -m

I also set ip_forward:
echo "1" > /proc/sys/net/ipv4/ip_forward


Then, in dom0 I try my LVS:
lynx http://192.168.200.180:8080
but I only get "making http connection to xxxx..."


Tomcat logs in both VMs don''t report the connection.
TCP sniffer in VM10/20 reports:

Any ideas why this doesn''t work? How should I do it? Any tutorial/howto
help is appreciated.


Thanks in advance,
