Starting today you can download the Windows Server 2008 R2 SP1 beta release. For Hyper-V this specifically means that you can start evaluating the following new Hyper-V features:
- Dynamic Memory – the new feature that allows Hyper-V to dynamically change the amount of memory assigned to a virtual machine at run time, to get higher consolidation ratios. I spoke about this at TechEd US 2010 – and you can watch the movie here.
- RemoteFX – provides support for rich graphics (Silverlight, 3D, etc…) when using Hyper-V to host desktop virtual machines.
You can register to download the beta here: http://www.microsoft.com/windowsserver2008/en/us/sp1.aspx
Note that while registration is required, there is no approval process and you will get immediate access to the bits.
