While I am all for virtualizing, it doesn't help security. It just moves the exploit from your OS into your hypervisor. Even worse, you add a whole new level of exploitable code.

The difference here is, you might feel safer but you are still in the exact same position as before, a bug in your hypervisor/Meta-OS screws you. I'd argue that is a harmful comfort.

The idea is that hypervisor is significantly smaller than the OS/kernel, so there will be less bugs. Not that they never happen, Xen had one recently.
