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.
