ESX is a bare metal install, so the VM's run under VMware directly.

You can run the linux cluster nodes as VM's within ESX, and use the
VMware infrastructure as a fencing mechanism (quite a few people do
this for their test clusters, we are one of them)

Were you get the biggest win with ESX is when you run multiple ESX
nodes together, with some shared storage and you get a VMware cluster.
This allows VM's to float across physical hardware to balance out the
load. I won't go into it any further, there's plenty of reading on
their website.
