Windows 8 includes its own copy of Hyper-V BUT
it can only be installed if the processor supports SLAT (called EPT by Intel and NPT by AMD) - you can use CoreInfo from sysinternals to determine if a processor supports these.
As best I can tell, all i7 processors support this, only one or two i5s do and the Xeons do. AMD have a list of what does and doesn't support it, but I have one that is listed and it must be an old stepping as in practice it did not support it.
So unless I have missed something along the way, Hyper-V on Windows 8 isn't a cert and depends on whether your processor has the right hardware features. Based on my limited digging around, most laptops probably won't support it.
If anyone knows otherwise, please post and correct me, as I would like to be wrong so that I can run Windows 8 with Hyper-V on a couple of older machines for testing.
