In this chapter, we discussed various virtualization techniques. We discussed virtualization as well as the tools and packages that help in creating and running a virtual machine. Also, you learned about the ways we can view, manage, connect to, and make use of the applications running on the virtual machine. Then, we saw the lightweight version of Ubuntu that is fine-tuned to run virtualization and applications on a virtual platform. At the later stages of this chapter, we covered how to build a virtual machine from a command line, how to add packages, how to set up user profiles, and the steps for first boot and first login.

In the next chapter, we will study cloud and OpenStack, how to set up Ubuntu with OpenStack, and more.
