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 increasing TLB cache efficiency. It will ensure that the guest has 100% dedicated RAM that will never be swapped out.

OpenStack Nova Specifications
This git repository is used to hold approved design specifications for additions to the Nova project. Reviews of the specs are done in gerrit, using a similar workflow to how we review and merge changes to the code itself.
The layout of this repository is:
specs/<release>/
You can find an example spec in doc/source/specs/template.rst.
Specifications are proposed for a given release by adding them to the specs/<release> directory and posting it for review. The implementation status of a blueprint for a given release can be found by looking at the blueprint in launchpad. Not all approved blueprints will get fully implemented.
Specifications have to be re-proposed for every release. The review may be quick, but even if something was previously approved, it should be re-reviewed to make sure it still makes sense as written.
Prior to the Juno development cycle, this repository was not used for spec reviews. Reviews prior to Juno were completed entirely through Launchpad blueprints:
http://blueprints.launchpad.net/nova
Please note, Launchpad blueprints are still used for tracking the current status of blueprints. For more information, see:
https://wiki.openstack.org/wiki/Blueprints
For more information about working with gerrit, see:
https://wiki.openstack.org/wiki/Gerrit_Workflow
To validate that the specification is syntactically correct (i.e. get more confidence in the Jenkins result), please execute the following command:
$ tox
After running tox, the documentation will be available
for viewing in HTML format in the doc/build/ directory.
