Hyper-V Server 2008 R2
While continuing to develop Windows Server 2008 R2, Microsoft is developing R2 version of it’s free virtualization product, Microsoft Hyper-V Server 2008. As I said in my first post about Hyper-V Server 2008, Hyper-V Server 2008 is basically Hyper-V-only product (Microsoft is promoting it as a product, not as a operating system), that enables you to have Hyper-V on your machine without need to buy Windows Server 2008. There are some cool improvements in R2 version, and here is the list that compares Hyper-V Server 2008 with Windows Server 2008 with Hyper-V role installed.

As you can see, in R2 version you can have more sockets, more cores, more memory, but I think the biggest news is ability to have quick and live migration and failover clustering. Compared to Windows Server 2008, the biggest change is the price. While Hyper-V Server 2008 R2 is free, it lacks virtualization rights for guest. While using Hyper-V Server 2008, you have to pay licence for every guest operating system, but while using Windows Server 2008 you have some free licence for guest operating systems. For example, when you buy Windows Server 2008 Datacenter, you get licence for home OS and for 4 guest operating systems, which is total 5 licences for one price. So, you should use Hyper-V Server 2008 R2 only if you plan to install your existing operating systems for which you already have licence as guest machines, or you plan to install some free Linux machines as guest OS.
Hyper-V Server 2008 R2 is now in Release Candidate status, you can download it from Hyper-V Server 2008 R2 official web page.
