Mastering KVM virtualization is a complete guide to understand KVM virtualization. Mastering KVM Virtualization is a culmination of all the knowledge we gained by troubleshooting, configuring and fixing bug on KVM virtualization. We authored this book for system administrators, DevOps practitioners and developers who have a good hands-on knowledge of Linux and would like to sharpen their skills of open source virtualization. The chapters in this book are written with a focus on practical examples that should help you deploy a robust virtualization environment, suiting your organization's needs. Our expectation is that, once you have finished the book, you should have a good understanding of KVM virtualization, its tools to build and manage diverse virtualization environments.

● Humble Devassy Chirammal
● Prasad Mukhedkar
● Anil Vettathu

5. What this book covers?
● Chapter 1, Understanding Linux Virtualization, talks
about the prevailing technologies used in Linux
virtualization and their advantages over others. It
starts with basic concepts of Linux virtualization and
advantages of Linux-based virtualization platforms and
then moves on to hypervisor/VMM. This chapter ends
with how Linux is being used in private and public
cloud infrastructures.

6. What this book covers?
● Chapter 2, KVM Internals, covers the important
data structures and functions which define the internal
implementation of libvirt, qemu, and KVM. You will also
go through the life cycle of vCPU execution and how
qemu and KVM perform together to run a guest
operating system in the host CPU

7. What this book covers?
● Chapter 3, Setting up a KVM Virtualization
Environment Using libvirt, tells you how to set up your
Linux server to use KVM (Kernel-based Virtual
Machine) and libvirt. KVM is for virtualization and libvirt
is for managing the virtualization environment.You will
also learn how to determine the right system
requirements (CPU, memory,storage, and networking)
to create your own virtual environment

8. What this book covers?
● Chapter 4, Getting Started with libvirt and Creating
Virtual Machines, will tell you more about libvirt and
its supported tools, such as virt-manager and virsh.
You will dig more into the default configurations
available in libvirt. You will install a new virtual
machine using virt-manager as well virt-install and also
learn about advanced virtual machine deployment
tools, such as virt-builder and oz.

9. What this book covers?
● Chapter 5, Virtual Storage and Network, is one of the most
important chapters that teaches you about virtual networking
and storage, which determine the QoS of your virtual machine
deployments. In virtual networking, you will learn in detail about
bridging, different bridging concepts, and the methods you can
adopt for a fault tolerant network layer for virtual machines. You
will understand how to segregate the network with the use of
tagged vLan bridges. In storage, you will learn how to create
storage pools for our virtual machines from storage backends
such as fiber channel (FC), ISCSI, NFS, local storage, and so
on. You will also learn how to determine the right storage
backend for your virtual machines.

10. What this book covers?
Chapter 6, Virtual Machine Lifecycle Management
and Migration, discusses the tasks of managing
virtual machines. You will learn about the different
statuses of virtual machines and methods to access a
virtual machine that includes spice and VNC. You will
understand the use of guest agents. You will also learn
how to perform offline and live migration of virtual
machines.

11. What this book covers?
● Chapter 7, Virtual Machine Templates and
Snapshots, tells us how to create templates of
Windows and Linux for rapid VMs provisioning. The
chapter will also teach us how to create external and
internal snapshots and when to use which snapshot.
Snapshot management, including merge and deletion
is also covered with snapshot best practice.

12. What this book covers?
● Chapter 8, Kimchi, An HTML5-Based Management
Tool for KVM/libvirt, explains how to manage KVM
virtualization infrastructure remotely, using libvirt-
based web management tools. You will learn how to
create new virtual machines, remotely adjust an
existing VM's resource allocation, implement user
access controls, and so on over the Internet using
Kimchi WebUI. It also introduces VM-King, an Android
application that lets you manage KVM virtual
machines remotely from your Android mobile or tablet

13. What this book covers?
● Chapter 9, Implementing Software-Defined
Networking for a KVM Virtual Environment, covers
the use of SDN approach in KVM virtualization using
Open vSwitch and supporting tools that include
OpenDayLight SDN controller. You will learn about
Open vSwitch installation and setup, creating vLans
for KVM virtual machines, applying granular traffic and
policy control to KVM VMs, creating overlay networks,
and port mirroring and SPAN. You will also learn how
to manage Open vSwitch using OpenDayLight SDN
controller.

14. What this book covers?
● Chapter 10, Installing and Configuring Virtual
Datacenter Using oVirt, oVirt is a virtual datacenter
manager and is considered as the open source
replacement of Vmware vCenter. It manages virtual
machines, hosts, storage, and virtualized networks. It
provides a powerful web management interface. In this
chapter, we will cover oVirt architecture, oVirt engine
installation, and oVirt node installation

15. What this book covers?
● Chapter 11, Managing oVirt virtual datacenter, tells
us how to initiate an oVirt datacenter in order to start
your first virtual machine. This initialization process will
walk you through creating a datacenter, adding a host
to datacenter, adding storage domains, and its
backend. You will learn about configuring networking

16. What this book covers?
● Chapter 12, Introduction to Openstack, covers the
most popular open source software platform to create
and manage public and private IaaS cloud. We will
explain the different components of OpenStack. You
will set up an OpenStack environment and will start
your first instance on it.

17. What this book covers?
● Chapter 13, Performance Tuning and Best
Practices in KVM, tells us how performance tuning
can be done on a KVM setup. It will also discuss the
best practices that can be applied in a KVM setup to
improve the performance.

18. What this book covers?
● Chapter 14, Migrating from Physical to
Virtualization and Cloud, will tell you how to migrate
your existing virtual machines that are running on
proprietary hypervisors to a truly open source KVM
hypervisor using virt-v2v tool. You will also learn how
to migrate physical machines to virtual machines and
run them on the cloud.
