So this mornings news from Alessandro is the release of Hyper-V - Download a trial here.
I have also included at the bottom of this post a number of links that Justin Zarb helped collate regarding where to find all kinds of info relating to Hyper-V

After over three years of development (the product was originally announced at WinHEC 2005 conference) Microsoft finally releases today its first bare-metal virtualization platform: Hyper-V.
During this very long process the product was delayed, changed name, and lost some planned key features.
Unlike Virtual Server and Virtual PC, Hyper-V is a type-1 virtual machine monitor (aka hypervisor) which features an architecture very similar to the one used by Xen and its commercial derivatives.
This allows a direct comparison with platforms like Citrix XenServer, Virtual Iron, the upcoming Sun xVM Server and obviously with VMware ESX.
Unlike the latter, Hyper-V adopts a microkernel developed from scratch (so it's not the Windows kernel) which is less than 1MB in size and delegates most of the tasks to a so called Parent Partition.
Depending on the configuration you adopted, the parent partition automatically loads a full copy of Windows Server 2008 or the new Windows Server 2008 Core.
Being a first generation product, Hyper-V cannot really compete with the above in features, but it clearly offers a performance boost (up to +107% in case of disk I/O activity) and some much deserved improvements over Virtual Server 2005 R2:
- Support for 32bit and 64bit virtual machines
- Support for up to 4 virtual CPU per VM (the actual number depends on the guest OS)
- Support for up to 64GB RAM per VM
- Support for the Windows 2008/2003/2000, Windows XP/Vista and Novell SUSE Enterprise Linux guest operating systems
- Quick Migration (the capability to suspend, migrate and resume a VM from one host to another)
- Automatic patching through Windows Update and WSUS
……
Microsoft Hyper-V is fully integrated with Windows Server 2008 64bit so any download of the OS includes it. Download a trial here.
For those customers already using the beta or the release candidate of Hyper-V, the product will be updated through the Windows Update service beginning July 8.
To demonstrate how much the company bets on this new product, Microsoft is internally adopting Hyper-V since a while and already migrated inside its virtual machines all the web front-ends that serve TechNet and MSDN websites.
Now the customers wait for the upcoming System Center Virtual Machine Manager 2008, currently in beta, to centrally manage Hyper-V (along with Virtual Server and VMware ESX), and MAP 3.1, in beta as well, to perform accurate capacity planning.
