I agree the answer to the question, "does virtualization slow systems down" is different if one means virtualization per se than if one means virtualization in practice.

In the original comment, I thought I saw questioning of the very concept of virtualization -- i.e. why is everyone rushing toward this thing if it costs so much speed? So in addition to pointing out what I think the benefits are supposed to be, I also opined that it doesn't cost speed. I think the virtualization that people are presenting as the next big thing is virtualization done right, not necessarily what is practical today. E.g. companies are introducing new products specifically to enable virtualization.
