Requirements

In order to be able faults with Tobiko you need an RC file for your OpenStack hosts (not the instances which run on OpenStack hosts) Using this RC file, Tobiko will be able to generate an os-faults configuration for you automatically. If you already have os-faults configuration file, you don’t need this requirement.

CLI

In order to restart openvswitch service, run the following command:

tobiko-fault “restart openvswitch service”

Python API

You can also use faults in your tests. Warning: running a fault in a test while other tests are running in parallel might have negative affect on your other tests.

from tobiko.fault.executor import FaultExecutor fault = FaultExecutor() fault.execute(“restart openvswitch service”)

Missing services & containers

What to do if the service or the container I’m trying to control is not part of os-faults configuration? In that case please submit a patch to Tobiko to add it to tobiko/fault/templates/os-faults.yml.j2 template.
