I think you'll need to run the N1k virtual switch in order to implement that:

If I were you, I would think very hard before implementing N1K in your VM
environment.  Although it has lots of nice bells and whistles and makes a
pleasant change from the feature-free vmware switching environment, it is a
cow to maintain.  Check out the 45 page upgrade guide for NXOS 4.2:

In fact, it looks like it's been simplified by scripting chunks of the
compatibility matrices that they used to supply with previous version.
