  • Publication number: 20240126695
    Abstract: Various embodiments are generally directed to virtualized systems. A first guest memory page may be identified based at least in part on a number of accesses to a page table entry for the first guest memory page in a page table by an application executing in a virtual machine (VM) on the processor, the first guest memory page corresponding to a first byte-addressable memory.
