Is there such a thing as an OS-less VM hypervisor? More specifically, a 
hypervisor which is its own OS in a way, you boot it directly (not 
booting Linux/Windoze then starting the hypervisor) and pretty much the 
only thing you can do once booted is starting virtual machines.

I suspect this is the case but I am not familiar with hypervisors.
I also suspect that many/most/all are really Linux under the hood.
