I just noticed that Microsoft has finally released Hyper-V, a key feature of Windows Server 2008. As per the official site of Windows Server 2008, it has now released to manufacturing (RTM) and is available for deployment into production environments.
As a Hyper-V user, I have been waiting for the final release for months. Now the existing Hyper-V users may download this update to deploy it on their Hyper-V farm, or simply use Windows Update to upgrade a single W2K8 server. MS KB article Q950050 gives the details.
The official announcements:
1. Microsoft’s Hypervisor Technology Gives Customers Combined Benefits of Windows Server 2008 and Virtualization
2. Virtualization and Consolidation with Hyper-V
