Public bug reported:

Description:

Extended Page Table Accessed and Dirty bits (EPT A/D bits)-This
technology improves performance during memory migration and creates
interesting opportunities for virtualized fault tolerance usages. You
probably already understand that guest OS expects contiguous physical
memory, and the host VMM must preserve this illusion. EPT maps guest
physical address to host address that allows guest OS to modify its own
page tables freely, minimizes VM exits and saves memory.

Target Kernel: TBD
Target Release: 17.10

** Affects: firefox (Ubuntu)
     Importance: Undecided
