Abstract
A virtual machine is instantiated. Pages of memory being accessed by the virtual machine are monitored. A hint stored in an extended page table associated with a page of the pages of memory being accessed by the virtual machine is inspected. A response to access of the page is based on the hint stored in the extended page table associated with the page.
