Have you tried installing and running Microsoft's Hyper-V yet? What about on a 16 Core AMD Opteron system? Well the folks over at HPC Systems have and they are sharing their thoughts and results with you. Check it out:
After a successful install and test of x86 Windows Server 2008, it was time to put the x64 version through the same test.
We will talk about the x64 installation and experiences in another post.In this post, we will focus on the Hyper-V installation, configuration and experiences on our 16 core AMD Opteron server, A5808-32.
Hyper-V is the new Microsoft hypervisor technology included with certain SKUs of Windows Server 2008 x64 version. Hyper-V, included in the Windows Server 2008 RC1, is still in beta stages.
Installation:
Hyper-V is a new server role. This role has to be added after Windows Server 2008 installs and boots up. This installs the Hypervisor and reboots the server.

Now a new role shows up under “Roles” in the “Server Manager”. The new role is “Hyper-V” and has the new category “Microsoft Hyper-V Servers”. Your server will show up under this category. In the future, we may see other categories than just “Microsoft Hyper-V Servers”. This could be a place holder for the future management framework talked about here.
Creating a new VM is pretty straight forward. Select New->Virtual machine from the Server Manager and follow the wizard. Here is a screen shot of FedoraCore 6 x86_64 installation. Look, Ma … Linux on Windows!
