Hello, all -

I am curious as to which scheduling method I should think about using.

I'm brand new to LVS, and don't think I quite understand the concept.
What I was looking for, was a system that would provide load balancing
and distribution,

looking at your original posting again, I still say the answer is yes LVS can do it.

and the load balancer or distributor itself (LinuxDirector?) would be aware of the states of the machines for which it balanced (RealServers?),

yes if you mean tcp states

and would distribute the load according to the least loaded machine.

LVS is aware of the number of connections to the realservers and schedules the next connection in a manner dependant on the scheduler (eg round robin, least connected...) However LVS doesn't know about the load on the realserver, so Horms is right - go see Jeremy project on the Redfishsoftware site. However if the director is balancing enough connections, the load will even out on the realservers.
