Windows was "company policy". Because i still retained the original installation as a VM they didn't notice that i ran a real OS underneath.

It is aimed at mass-virtualisation and quite similar to what Sun called "zones" and IBM calls WPARs: a very, very manageable "chroot"-like environment. Because it is fully paravirtualised it has very little overhead, especially compared to fully virtualised environments like VMware or VirtualBox, on the other hand all the guest systems share a common kernel, so different guest systems are not possible.

I hope this helps.
