I used the Windows 7 Ultimate 64-bit RC (Release Candidate) with Virtual-PC RC and Windows XP Mode RC to verify if it can work. Here is the picture.
Please note many caveats.
The most important ones:
- PC has to have a CPU which support Intel Virtualization Technology (Intel VT-x) or AMD's equivalent AMD-V.
- BIOS must have the capability to turn VT feature on. (Some BIOS implementations block such feature.)
- I am just testing the free Win7 evaluation (available for download until 8/20/2009). Windows Virtual-PC/Windows XP Mode is not supported in entry level Microsoft licensing scheme (e.g., Windows 7 Home Premium.)
- and more
More details to follow.
