Great, thanks!

But does that mean I would need two separate management systems? One to do
the LVS and a separate one just for the mysql HA ? Can I have the mysql HA
management be done within the same system that also does the LVS? 

In other words, can I have heartbeat managing mysql, and at the same time
also running integrated with LVS?
