Wait... I just realized, that you CAN do that too!
I THINK that when you buy a Windows Server 2012 R2 license, it comes with one license built-in to you can install it again as virtualized operating system on top of itself once you activate the Hyper-V on it but you can check this with Microsoft support line, the licensing section. At least, I remember you could do that with Windows Server 2008 R2 with Hyper-V so I assume it's the same for 2012 R2 as well but better check with them before you order the license.
If you buy from DELL or HP, they can help you with it. I think when you build a server on their Web site, you can choose operating system and such. Also, I THINK that there was a version of Windows Server xxx without Hyper-V so when you buy it, make sure it is WITH Hyper-V. (The cost was the same I believe, Microsoft and their moronic licensing but that's another subject... )
