Oracle does not certify to hardware ... Oracle certifies to operating systems. So while you are in some sense correct you are not in another.

 From my experience with Oracle when Apple was cooperating ( I know what Oracle requires in the way of hardware to support a port ... and the amount of hardware, I can't discuss exact numbers, was so substantial that it really does give them the ability to create a massive number of environments.

Also consider that Oracle expects you, the customer, to read the support matrix and to install based on the docs posted at So in that sense they can, in fact, do so.

What virtual environments do is make it harder to "support the operating system."

I've no doubt cost enters into the equation given Oracle is not a non-profit and has no desire to become one. But in this case I doubt the cost of VMWare training, or Solaris Containers training is significant.

That's not what I see here:
