In this chapter, we looked at adding images to the Glance image registry for you to learn how to get a prebaked Glance image and how to build your own Glance image. With a disk image stored in Glance, there is now a disk that the instances can copy and use to boot from the time they are spawned. Now that we have created users and stored disk images to launch with, the final resource that needs to be created before we launch an OpenStack instance is a virtual network. In the next chapter, we will use Neutron to create a virtual network fabric for an instance to be connected to.
