Mike, 1. I'm not aware of a load balancing capability in the VCL, in terms of spreading out reservations on servers across hypervisors. Although we have 224 VMs in our environment spread across 24 vmhosts, and the randomness of it seems to suffice. We don't have the VM's assigned in order, i.e. vm1-vm8 on vmhost1, vm9-vm16 on vmhost2, etc. They're all kind of mixed up, not sure if that helps the randomness or not. Maybe someone else on the list has a clever way of doing it.
2. We are using the free version of VMware ESXi 4.1, and it licenses 2 physical CPUs (1-6 cores each), so we get 12 cores per machine, which is the max we have anyway.

I've been tasked with building out and managing a VCL implementation that will utilize VMWare ESXi 4.1 hypervisors across 5 separate servers. I have trolled the existing documentation and listserv archive, but I have two burning questions: 1. I've read in another thread that VCL doesn't have load balancing capabilities per se as part of the scheduler. How does VCL equalize the load of virtual machines across several hypervisors? 2. I've found that the "free" VMWare hypervisor 4.1 license caps out at one physical processor (with 6 cores). Are most folks running a non-free VMWare license alongside VCL? I greatly appreciate any assistance that current VCL users and the dev team can provide!
