Check out IT magazines like PC World. Virtualization’s been written about extensively over the past few years. You will find a lot of articles.
If its management whos asking you to do this, its a wild goose chase. The person/s dont feel comfortable with virtualization. You can point to articles. But a better way to overcome their resistance is to show them what it does. Ask them about their specific concerns, and then answer those.
Stay with it, and you will succeed.
