Well, I'm not exactly sure what you are trying to do here.
Basically, lets say you have your 6 real servers sitting behind your
director. A connection to port 1234 comes in, do you want *all*
connections to go to the same server each time? If so, then LVS might
not be what you want.
If you want to balance the traffic behind all 6 servers, then yes, you
want LVS. If you want auto fail over between a pair of servers, then
you want to use Heartbeat only.
With game servers, you probably want all connections to go to the same
server correct? LVS might not be the right solution for you unless
all the users are able to inter operate between all the real servers,
in which case LVS would be ideal. Otherwise, to achieve just high
availability, use Heartbeat.
