Lets back up a second.
VMware is a tool that allows you to run a set of virtual
machines on one physical machine. VMware ESX has the concept of
a 'cluster' whereby VMs will automatically migrate between
physical machines to balance load, or automatically reboot onto
a working node if the primary as failed. This feature requires
that all of the servers involved used a shared storage device.
For server applications, you could certainly run the servers
inside a VMWare VM.
Assuming you had multiple VMs performing a given webhosting
task, you could use Linux LVS to balance the incoming traffic
across them.
However, Linux LVS doesn't have the concept of 'adding machines
to a cluster' in the same sense that a NUMA supercomputer can add
nodes and treat them as a single large image. The physical
machines are still disparate.
I don't know that it makes any sense to have your desktops /
workstations run VMWare and then run Windows on top of it. It
would make more sense to have your desktops run a cut down
Windows natively, then RDP into a VM running on dedicated VMWare
servers.
Perhaps you could give us a better idea of what you are trying
to accomplish?
