I recently got a Mac Pro that has 6 Cores, 16 GM RAM, and 16 TB disk space. I want to isolate part of the hardware resources (say 4 cores and 10 GB RAM) for building VM using Xen. The computer has Mac OSX Maverick installed. I am not sure if I can install Xen to provision a VM on top of the OSX. If yes, can I still work on the Mac Pro while running a VM on top of it? The whole point of the isolation is I want to do scientific computation on the VM while writing code on the Mac Pro with the remaining 6GB RAM and 2 CPU Cores.
