Actually it won't work _now_ with KVM, but it could.
It would be a good idea to map the multiple CPU AddressSpaces to KVM's
own multiple address spaces. It's possible to modify i386 to do this,
using address space 0 for normal operation and address space 1 for SMM,
just like KVM.
More on this as I reply to the remainder of the series...
