      power management has been added to nova.
      we should default to enabling this in the next gen installer.

      to do this we should set
      [libvirt]
      cpu_power_management=true

      https://docs.openstack.org/nova/latest/configuration/config.html#libvirt.cpu_power_management

      this will enable the default cpu_state cpu_power_management_strategy

      https://docs.openstack.org/nova/latest/configuration/config.html#libvirt.cpu_power_management_strategy

      so no other configuration is required.
