Cloned from launchpad blueprint https://blueprints.launchpad.net/nova/+spec/virt-driver-large-pages.

Description:

This feature aims to improve the libvirt driver so that it can use large pages
for backing the guest RAM allocation. This will improve the performance of
guest workloads by improves TLB cache efficiency. It will effectively create
the concept of "dedicated RAM" guest instances.
