Microsoft does it again, promise great cool features and even demo them. They let us wait for months/years and then just drops the cool stuff for a "future release" [:@]. Just like the Windows Server team did with R2 at the time.
 
They drop nearly all the great selling points in Viridian: No live Migration, no hot add of anything[W], CPU core limit drops from 32 to 16.

Well lets hope they will get it ready in Longhorn Server SP1. Till then long live Vmware ESX! [I]

Today Microsoft announced that a beta version of Windows Server virtualization will be available with the release to manufacturing (RTM) version of the next-generation of Windows Server, codename "Longhorn," in the second half of the year. This pre-production version of Windows Server virtualization will allow a broad set of customers and partners to familiarize themselves with this important part of Windows Server "Longhorn," and begin testing workloads and applications in high availability/disaster recovery, server consolidation, dynamic datacenter, and test and development scenarios. A final, production version of Windows Server virtualization is scheduled to be released within 180 days of the release of Windows Server "Longhorn."

"So we had some really tough decisions to make.  We adjusted the feature set of Windows Server virtualization so that we can deliver a compelling solution for core virtualization scenarios while holding true to desired timelines. Windows Server virtualization is a core OS technology for the future, and we chose to focus on virtualization scenarios that meet the demands of the broad market – enterprise, large organizations, and mid-market customers. We continue to offer great technology and successful strategies for enterprise customers by broadly investing in the several areas.

So we are making the following changes, and postponing these features to a future release of Windows Server virtualization:
·         No Live migration
·         No hot-add resources (storage, networking, memory, processor)
·         Support limit of 16 cores/logical processors (e.g., 2 processor, quad-core systems is 8 cores; or 4 processor, quad-core system is 16 cores)
