METHOD FOR OPTIMIZING VIRTUALIZATION TECHNOLOGY AND MEMORY PROTECTIONS USING PROCESSOR-EXTENSIONS FOR PAGE TABLE AND PAGE DIRECTORY STRIPING |
摘要 |
In a virtualized processor based system causing a transition to a virtual machine monitor executing on the processor based system in response to a modification of a page table of a guest executing in a virtual machine of the processor based system, and the virtual machine monitor responding to the transition by performing a verification action, and for each bit modified in the page table of the guest, reading a status indicator for the bit to determine if the bit is significant; and causing the transition only if the status indicator for any bit modified in the page table indicates that the bit is significant.
