If there where 10's of thousands of Mainframes in a company then you'd be hearing more about z/VM But there's not. So the focus is on the Intel world where this happens. At least that's my take on it. Can z help? Sure. But not every company wants a whole new support structure or is willing to pay for one just to run on z. and letting the Intel guys manage Linux for z is a bad idea.
