For this technique we call it Shadow page table technology.Since then, Intel has pioneered the EPT (Extended page Tables) technology, which, compared to the shadow page table technology, reduces the difficulty of memory virtualization, and the EPT technology directly implements the linear address in the guest OS to the guest in hardware. The physical address in the OS is then converted two times to th
