20.6. Memory Backing
Memory backing allows the hypervisor to properly manage large pages within the guest virtual machine.
<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>
