      Investigate the performance implications of free page reporting.  This includes:

      • CPU overhead: How much CPU will it take on both the guest and the hv to return memory and reacquire it.  This probably requires a bit of a thrash workload on the guest, something like lots of processes on the guest that allocate lots of memory, touch it all randomly, and exit.
      • Memory savings: Does enabled FPR lead to a lower per-node memory consumption (with non-memory-intensiveguests) compared to disabled FPR?
