Virtual PC 2007 has RTM'ed (kinda same as lift-off). It is now available for free on the Microsoft download website.
Some of the new features that will be available with Virtual Server 2005 R2 SP1 are in VPC 2007:
- Support for hardware virtualization AMD-V and Intel-VT
- 64-bit host support (guest support will come with Windows Server Virtualization in the Longhorn Server timeframe)
- Vista guest and host support
This and more is available now and for free. Yeah!
