I have ESX set up and running in VMworkstation.  It's pretty slick what you can do with this  

I tried doing the same for Server 2008 R2.  While I can install it fine, when I try to add Hyper-V as a feature, it has a fit.  I changed the CPU to IntelVT, but that didn't do the trick.
Is there a way to get this running inside VM workstation?
