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>
