I hate virtualization with a passion, because it's just more crap that doesn't work written by people that shouldn't touch computers.

In theory, it's great. In practice, if you need to get "support" from someone else, it's not so great anymore, as all these companies have been discovering.

I would use VM technology if whoever wrote it would provide me with a contract saying that if anyone were to find just one program that would crash their VM (while not crashing a real machine) or miscompute, that I would get a billion dollars.

To answer your question: I was smart enough to never use it in the first place.
