VMware Integrated OpenStack supports virtual CPU pinning. When running latency-sensitive applications inside a virtual machine, you can use virtual CPU pinning to eliminate the extra latency that is imposed by virtualization.
You use the OpenStack CLI or API to configure a Nova flavor with extra specs to use pinned virtual CPUs. The flavor includes a dedicated CPU policy setting to ensure that the entire physical core is allocated to a virtual CPU of an OpenStack instance. New VMs launched with the flavor will have the low latency settings.
- Using SSH, log in to the OpenStack Management Server.
- Configure the Nova flavor.
