It would be good to run both Windows vms and linux vms. Early use would be maintaining multiple Windows installs using only one desktop computer with plenty of cores and memory. I would be starting with a Windows host, but probably later switching to a linux host after i learn more about linux.
Free is good, but reliability and ease of use are better.
What is the current Slashdot choice for a vm beginner:
vmware, zen, virtual box, etc. ???

Cray’s XC30 isn’t the only supercomputer aiming for that 100-petaflop crown. China’s Guangzhou Supercomputing Center recently announced the development of a Tianhe-2 supercomputer theoretically capable of 100 petaflops, but that system isn’t due to launch until 2015. Cray also faces significant competition in the realm of super-computer makers: it only built 5.4 percent of the systems on the Top500 list, compared to IBM with 42.6 percent and Hewlett-Packard with 27.6 percent. However, Cray also leads Appro (3.6 percent) and SGI and Bull (3.2 percent each)."
