Q. Does the Windows Virtual PC software used by XP Mode in Windows 7 use the same technology as Hyper-V?

A. No. Windows Virtual PC is primarily based on Virtual Server, with certain elements of Hyper-V added, such as the VMBus used for USB redirection. It isn't a true type 1 hypervisor running in Ring 0 like Hyper-V; it's a hybrid hypervisor. Because the product will deal with desktop OSs, it has some features that a hypervisor impedes, such as power management for sleep functions.
