Summary

In this chapter, we covered the inner workings of KVM and its main partners in Linux virtualization – libvirt and QEMU. We discussed various types of virtualization – binary translation, full, paravirtualization, and hardware-assisted virtualization.

This gave us the necessary technical know-how to understand the topics that will follow in this book – everything ranging from how to create virtual machines and virtual networks to scaling the virtualization idea to a cloud concept. Understanding these concepts will also make it much easier for you to understand the key goal of virtualization from an enterprise company's perspective – how to properly design a physical and virtual infrastructure, which will slowly but surely be introduced as a concept throughout this book.
