My question is : suppose I have 2 NICs on each real server. Is there any advantage of configuring the VIP on the loopback device against configuring it on eth1 ? should configuring the VIP on eth1 work ?
In the early days (<=2.2) any device on the realserver was OK for the VIP (eg dummy0, eth1). I haven't checked since then, but all you're looking for is an address that will deliver packets locally. Since then the linux kernel has gotten a lot more anal/precise about such things and much that we used to be able to do in 2.0.x doesn't work anymore and I can't see any reason why the old behaviour was wrong. So it's reasonable to think that eth1 should work, but I haven't checked it for recent kernels
