Hyper-V is coming to Windows 8, but you must have a processor that supports SLAT. Virtual machines created with Virtual PC aren’t easily transferred to Windows 2008 Hyper-V and vice-versa. With Windows 8, it will be easy to move vhds from Windows 8 on your laptop or desktop to Windows 8 server and back again.
To find out if your processor supports SLAT, run coreinfo –v from a command window running as administrator. Download coreinfo from here.
Check the second column of the output for a – or a *. You want to see a *, which indicates a feature is supported.
My MacBook Pro supports SLAT as this output shows:
