Go and take a look at the download page for Windows Server 2008 RC1. It contains a link to a version with Hyper-V Beta. The Windows Server Division weblog has more details about the release.

Some critical new features in this release are:

  • Support for quick migration and cluster HA (16 nodes).
  • Installation from Server Manager.
  • Support for running on Server Core!
  • VSS support.
  • 64 GB of memory for a VM (just like in ESX 3.5).

Integration components are available for Windows Server 2003 and Windows Server 2008 (x86 and x64). Integration components for Linux are available in beta form.

Quite a surprising release. Everybody was expecting this only at the release of Windows Server 2008 in February.
