Issue with Xen and Linux Virtual Server

Hi there, I'm working with Xen over a debian box and I'm trying to get
to work some LVS with ldirectord. The network design looks like this:

Dom0 "public" ip: 192.168.0.122 (eth0)
Dom0 "private" ip: 172.16.1.129 (vif3.0)
DomU ip: 172.16.1.2

The conectivity is working fine. I can ping from de DomU tu anywhere
in the world. I also installed (using apt) an apache.

ldirectord is configured and running:

debian:~# ipvsadm -L -n
IP Virtual Server version 1.2.1 (size=4096)
Prot LocalAddress:Port Scheduler Flags
-> RemoteAddress:Port Forward Weight ActiveConn InActConn
TCP 192.168.0.122:80 rr persistent 300
-> 172.16.1.2:80 Masq 1 0 0

And the package are getting from de "world" to the realserver (DomU).
Apache's access logs told me that :-)

debian-web01:~# tail -f /var/log/apache2/access.log

192.168.0.131 is my ip address...

And I'm stucked here. I don't know where the problem can be. I hope
you can help me with this or give me and advice to get it to work.

Thanks a lot.
