Chapter 7. Installing Nova
With the basics and theory behind us, it is time to get hands-on with Nova and install the code on a server. In this chapter, we will walk through the installation and configuration of Nova on a single node with both the StackOps distro and Ubuntu packages. You’ll get a feeling for the complexities of implementing your design choices in actual usage. While these installations will be only single nodes, they will contain the entire array of OpenStack software and features.
Installing Nova with StackOps
As we described back in StackOps, StackOps provides a distro for OpenStack with a bare metal installer. The bare metal installer automates most of the installation and configuration tasks, leaving very little command line or configuration file editing for the administrator. It will install an operating system, necessary software packages, and Nova configuration files for us.

nova-api supporting both the OpenStack API and EC2 API
nova-objectstore (instead of Glance) for an image service
nova-volume with iSCSI volumes
nova-network using FlatDHCP ...
