I was talking to my friend and he told me that a new OS has come in the market that even if you root, you can't takeover the whole system. I was struck by that but after doing some research on how it works, I am pretty much convinced that more or less, at this point of time, one can't gain control of whole system even if the box gets rooted. It uses Hypervisor Abstraction Layer (HAL), Xen 4.4 virtualization technology and supports Debian Linux.
