In this chapter, we looked at creating networks, subnets, routers, and the preparation involved in using an external network with Open vSwitch. Using these resources, the necessary virtual networking fabric has been created for an instance to be launched on. Now that we have created virtual networks for the instances to attach to, let's get into launching instances. In the next chapter, we will do what we have been working towards—launch an instance. We will use Nova to launch an instance from the image that was imported and attach it to these virtual networking resources.
