The Virtual PC 2007 beta 1 is now available on Microsoft Connect.
What’s new in Virtual PC 2007 Beta
Hardware-assisted virtualization*
Virtual PC 2007 includes support for virtualization technology from Intel and AMD. By default, hardware-assisted virtualization is enabled if the feature is enabled on the physical computer. You can turn this assistance on or off for each virtual machine by modifying the virtual machine settings.
Support for Windows Vista as a host operating system
This beta release of Virtual PC 2007 introduces support for Windows Vista as a host operating system. The following versions of Windows Vista are supported: Windows Vista Business, Windows Vista Enterprise, Windows Vista Ultimate.
Support for Windows Vista as a guest operating system
This beta release of Virtual PC 2007 introduces support for Windows Vista as a guest operating system. The following versions of Windows Vista are supported: Windows Vista Business, Windows Vista Enterprise, Windows Vista Ultimate.
Support for 64-bit host operating system
This beta release of Virtual PC 2007 supports 64-bit host operating systems. However, there is no support for 64-bit guest operating systems.
* Installing Virtual PC 2007 Beta on a computer that has AMD hardware-assisted virtualization support and uses an x64 version of Windows as the host operating system may generate a bug check and shut down the operating system. This occurs because x64 versions of the Windows operating system protect a critical system register that Virtual PC 2007 modifies to enable hardware-assisted virtualization. You can resolve this issue by installing a hotfix prior to installing Virtual PC 2007. The hotfix is available and can be downloaded from this beta site by clicking on the ‘Downloads’ link on the left pane of this page.
