Well I think it's either that you applied "hidden" to eth0 on the

Great ! That was it. Now that I have the VIP as an alias on LB, it works.

Note to the documentation team : on Ubuntu 8.04, there is a trap with real
servers.
If you set arp_ignore/arp_announce configuration in /etc/sysctl.conf AND set
the VIP on lo:0 in /etc/interfaces. It seems that the interface is brought
up  *before* the sysctl commands are passed. You have to set the VIP
manually at the end of the boot process...

I will investigate further with Ubuntu team to find out why it behaves like
that.

Thanks for your help, regards.
