The product i am working on, Virtual Machine Manager, has just released to manufacturing (RTM is the keyword we use for this). In the next few hours, you should be able to download an evaluation version of the software (it expires 180 days later) from www.microsoft.com\scvmm.

 

If you want to learn more about the release of VMM, read this blog post by Zane. http://blogs.technet.com/virtualization/archive/2008/10/21/system-center-virtual-machine-manager-2008-rtms-and-what-i-m-hearing-from-customers-and-partners-about-microsoft-s-virtualization-solutions.aspx
