When working with these labs, people who have heard about the hypervisor integration
usually ask what is going to be different between the hypervisor and the current offerings or Virtual Server 2005 R2 Beta. In this link, you an find extensive information about the difference between them, but of special interest is the table below:
Virtual Server 2005 R2
Windows Server Virtualization
32-bit VMs
Yes
Yes
64-bit VMs

More than 32 GB per VM

This table only goes to show that Microsoft’s Virtualization strategy in the future will offer a lot more than Virtual Server. Keep in mind that these features will be available about 180 days after Windows Longhorn Server ships, so until then, we will just have to sit back and watch these long awaited features with a lot of patience.
