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
