You do not want to do this...I saw someone say you wanted to be on the
same subnet; I wouldn't even do it that way if it were me. I would run
serial cable direct or I would run crossover cable directly to
interfaces. The last thing you want is heartbeat flapping due to
latency. Usually heartbeat works well, but I have seen it bring up all
services/interfaces on all the servers which were failover for one
another. It is possible, and as you can imagine, it's not a case you
want a production environment to be in.

We use LVS (Linux Virtual Server) as our loadbalancer at the moment.

It's going to fail - it is just a matter of when.
