I just went looking for a decent comparison of Hyper-V in Windows Server 2008 R2 and Windows Server 2012. I obviously found this excellent document on download.microsoft.com – but couldn’t find these high-level bullets anywhere.

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.
