Hyper-V is available as both the FREE Hyper-V Server 2012 and as a role in Windows Server 2012.

If you are virtualising Windows Server workloads (and have licensed them correctly), Hyper-V is completely “free” – so save yourself a lot of money by NOT purchasing an additional virtualisation solution.
