2012 R2 SOFS Virtualization Question

Hi all,

New to Server 2012 and Hyper-V but trying to catch up quickly. I know that you cannot have the Hyper-V and SOFS roles at the same time but I am having a hard time finding clarification on the exact scope of that statement.

Does this mean that the SOFS instance, or cluster in my case needs to run on its own bare metal hardware, or can I have a 2012 R2 Hyper-V server hosting a 2012 R2 VM running the SOFS instance on the same hardware? 

I am looking to deploy a Hyper-V HA cluster along with a SOFS HA cluster using two beefy servers and 2-3 JBOD chassis. 

Thanks for the clarification.
