Mirantis Container Cloud (MCC) becomes part of Mirantis OpenStack for Kubernetes (MOSK)!

Starting with MOSK 25.2, the MOSK documentation set will cover all product layers, including MOSK management (formerly MCC). This means everything you need will be in one place. The separate MCC documentation site will be retired, so please update your bookmarks for continued easy access to the latest content.

Configure custom CPU topologies¶

Note

Consider this section as part of Deploy an OpenStack cluster.

The majority of CPU topologies features are activated by NUMATopologyFilter that is enabled by default. Such features do not require any further service configuration and can be used directly on a vanilla MOSK deployment. The list of the CPU topologies features includes, for example:

NUMA placement policies
CPU pinning policies
CPU thread pinning policies
CPU topologies

To enable libvirt CPU pinning through the node-specific overrides in the OpenStackDeployment custom resource, use the following sample configuration structure:

spec:
  nodes:
    <NODE-LABEL>::<NODE-LABEL-VALUE>:
      services:
        compute:
          nova:
            nova_compute:
              values:
                conf:
                  nova:
                    compute:
                      cpu_dedicated_set: 2-17
                      cpu_shared_set: 18-47
