- 1. Mastering KVM Virtualization A complete book about KVM
- 3. Who this book for ? This book is intended 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.
- 4. Authors ● 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.
