I completely agree with Bill Kish,
A Virtual Machine is just a piece of software which emulates (pretends), to be machine (computer) to do an abnormal task such as running Windows on a Macintosh computer for example, to occur via the trapping of computer instructions. It is quite literally a computer running ON a computer. One of the by-products of this is that the two systems can be entirely separated from each other, which allows a level of security that just can’t be matched.
So Bob you can think of going that way as well (If you have not already made up your mind).
