KVM Virtualization Cookbook

By: Konstantin Ivanov

Overview of this book

Virtualization technologies such as KVM allow for better control over the available server resources, by deploying multiple virtual instances on the same physical host, or clusters of compute resources. With KVM it is possible to run various workloads in isolation with the hypervisor layer providing better tenant isolation and higher degree of security. This book will provide a deep dive into deploying KVM virtual machines using qemu and libvirt and will demonstrate practical examples on how to run, scale, monitor, migrate and backup such instances. You will also discover real production ready recipes on deploying KVM instances with OpenStack and how to programatically manage the life cycle of KVM virtual machines using Python. You will learn numerous tips and techniques which will help you deploy & plan the KVM infrastructure. Next, you will be introduced to the working of libvirt libraries and the iPython development environment. Finally, you will be able to tune your Linux kernel for high throughput and better performance. By the end of this book, you will gain all the knowledge needed to be an expert in working with the KVM virtualization infrastructure.

OpenStack is a cloud operating system that simplifies the deployment and management of virtual machines or containers in a scalable and highly available way. It operates on pools of compute resources (physical or virtual servers) and provides an intelligent scheduling mechanism to select appropriate hosts, and to build or migrate VMs.

OpenStack allows an easier management of virtual images and provides a centralized way of creating and managing software-defined networks. It integrates well with a variety of external and internal projects in order to deliver user and service authentication. OpenStack modular design allows adding and removing services as needed where a minimal production deployment may consist of as few as two projects an image and compute service.

The following diagram shows the ever-growing list of OpenStack projects and the interaction between them:
