The biggest benefit of virtualization is usually said to be improved server utilization.

But why do I need virtualization for that?

Say I got N physical servers that are lightly used. Why don't I just combine all the apps on those N servers into 1 physical server? This way I don't incur the performance penalty of virtualization.

What does virtualization buy me in this case?
