1.3.2. Zero configuration

The Virtual Accelerator can be started without any configuration. It is called the zero configuration mode. In this case, the fast path uses one physical core per socket, and takes all supported physical network ports. Virtual network ports should be created on demand before starting a VM (see the Hotplug a virtual port section).

In most cases, zero configuration is enough and you’ll want to jump to the Optimizing performance section.

Expert users may want to fine tune the configuration in order to assign more cores to the fast path or restrict the NICs polled by the fast path. In this case, move on to the Configuration tuning section.

Note

The fast path is the Virtual Accelerator component in charge of packet processing. More details were provided in Data Plane section.
