I wonder which trick you use, since there is only one page table one

AMD K8 with the SVM feature has host and guest page tables and
address-space identifiers for the guests so their global TLB flushes
can be limited to their own address space...

Yeah, I know about the nested page tables on K8. But VMware will not
restrict themselves to K8 only, so they need a clever way to implement
shadow page tables on i386 chips without this feature.
