You need to consult the hardware documentation for this sort of
information.

In the Intel case you need the "Intel 64 and IA-32 Architectures
Software Developer's Manuals":

http://www.intel.com/products/processor/manuals/

For VMX you want volume 3 (AKA system programming guide), which comes in
two parts.

For AMD you want "AMD64 Architecture Programmer's Manual":

http://developer.amd.com/documentation/guides/pages/default.aspx

I think SVM is in volume 2.

Ian.
