Oh, and on second thoughts (now I have had my morning coffee) you wouldn't need to chop up the hardware, pre-allocated space, memory and load balancing might help with that, you wouldn't have to assign memory/other resources on a VM by VM basis, if your using one VM it would run with all the hardware available, until you wanted to use the other one, and unless your loading (running apps on) both at the same time it wouldn't be an issue, but for most people it would be a case of only using one VM at a time anyway...... Like the other day, I was messing around with workstation (which is installed on my works Win7) and I wanted to convert .vdi to .vmdk
