Note
Consider this section as part of Deploy an OpenStack cluster.
The huge pages OpenStack feature provides essential performance improvements for applications that are highly memory IO-bound. Huge pages should be enabled on a per compute node basis.
Since NUMATopologyFilter is enabled in a MOS deployment by default,
to activate the feature, you need to enable huge pages on the host as
described in Mirantis Container Cloud Operations Guide:
Enable huge pages in a host profile.
Note
The multi-size huge pages are not fully supported by Kubernetes before 1.19. Therefore, define only one size in kernel parameters.
