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

Starting with MOSK 25.2, the MOSK documentation set covers all product layers, including MOSK management (formerly Container Cloud). This means everything you need is in one place. Some legacy names may remain in the code and documentation and will be updated in future releases. The separate Container Cloud documentation site will be retired, so please update your bookmarks for continued easy access to the latest content.

Configure CPU isolation for a compute node

CPU isolation is a way to force the system scheduler to use only some logical CPU cores for processes. For compute hosts, you should typically isolate system processes and virtual guests on different cores.

For a compute node running Ubuntu 22.04 and newer supporting cgroup v2, use the cpushield HOC module to configure the CPU isolation. For the procedure, refer to Host operating system configuration.
