I have no idea what your question is as it doesn't appear to pertain at all to the thread title.
EDIT: I agree with your assesment that you are posting quite a bit. While this isn't a bad thing I would request that you do a bit more searching of the forums for these answers. As I said above, I have no clue what you are asking and if I did, I'd be more than happy to guide you to the answer of give the answer up front.
After reading the question I am thinking you are asking if a person can install a VM on FreeNAS 11. Of course you can. If this was the question then might I refer you to the user guide and to search the forums. There is a lot of material on using VMs becasue it's kind-of new and there are issues so people are talking about them and how to resolve those issues.
