摘要：
In one embodiment, a method includes creating a first working set of shadow page table hierarchies for a first processor of a plurality of processors, creating a second working set of shadow page table hierarchies for a second processor of the plurality of processors, keeping a record of modified guest page tables, and synchronizing each modified guest page table with a corresponding shadow page table in the first working set. For each modified guest page table in the modified guest page tables record, an entry includes an indication of which of the plurality of processors have a hardware translation lookaside buffer containing a writable reference to the modified guest page table.
