Currently, a lot of people believe that virtualization is the latest religion. If you read this site often, you might already know that I don't believe in that. But than again, I am not a religious person.

Virtualization on Linux needs five to six servers to reach break even. This means that unless you can mix several smaller companies' services onto the same hardware, virtualization on Linux is not financially interesting at all. And although some companies are small, they could still run applications that handle sensitive data such as financial data. This kills the financial reasons needed to skyrocket virtualization into the next galaxy. You see, to win a revolution in IT, you need to win it in all departments.
