Steven Bink reports the news that upcoming Virtual Server update, codename vNext, will not be able to run x64 guest OSes. Microsoft directly confirmed this on January, after several direct requests of the famous Windows blogger.
The good news is that vNext is instead going to support Intel Virtualization Technology and AMD I/O Virtualization Technology.
The product shipment is expected somewhere in the 2H 2006. At today no beta program is available.
