The purpose of this patch is to get Intel VT with EPT but without unrestricted guest working
for use on some older machines.


From: Kevin Pedretti 

Here's a patch that gets my 64-bit guest booting with nested paging on old Intel 
(Nehalem class) systems that do not have unrestricted guest support.  The only 
testing I've done is to boot the guest with nested paging and shadow paging.  
Both work.  I have not tried booting on a newer Intel system.

Not sure if this is the right way to go.  Please feel free to rework.
