20.6. Memory Backing

Memory backing allows the hypervisor to properly manage large pages within the guest virtual machine.
The optional <memoryBacking> element may have an <hugepages> element set within it. This tells the hypervisor that the guest virtual machine should have its memory allocated using hugepages instead of the normal native page size.

<domain>
  ...
  <memoryBacking>
    <hugepages/>
  </memoryBacking>
  ...
</domain>
