How to add NFS share as a "locally" attached volume in Server 2012 Hyper-V.

I am trying to create a network storage space, where I can export both Hyper-V and VMware VMs.  For VMware you can do this over SMB but it's ultra slow.  Hyper-V you can sort of do this via powershell from the host its self (forget the Hyper-V Manager...uggh), but I cannot get the import powershell command to work.

I have been able to attach "local" storage to these Hyper-V hosts using ISCSI, and export/imports work well.  But you cannot connect more than one host to a single LUN as I was hoping.  Oh well.  Anyway.

So now I am looking at NFS which is a cluster based file system that is supposed to be able to do what I am after.  IE single location, multiple servers attaching to it and seeing it as local storage, VM platform agnostic.  This of course maybe not correct and a lapse in my researching skills. :-P

However if it is correct logic, I am running into issues using the mount command via command prompt on server 2012 hyper-v, saying that mount is not a recognized command.  I try to install the client for NFS on both my Windows 8.1 pro laptop and on the Server 2012 Hyper-v and it's not even an option for add new Windows features.  How does one attach a Windows OS to a NFS volume as local storage and not a network drive?

Thanks :-)
