Mastering KVM Virtualization - Second Edition

By: Vedran Dakic, Humble Devassy Chirammal, Prasad Mukhedkar, Anil Vettathu

Overview of this book

Kernel-based Virtual Machine (KVM) enables you to virtualize your data center by transforming your Linux operating system into a powerful hypervisor that allows you to manage multiple operating systems with minimal fuss. With this book, you'll gain insights into configuring, troubleshooting, and fixing bugs in KVM virtualization and related software. This second edition of Mastering KVM Virtualization is updated to cover the latest developments in the core KVM components - libvirt and QEMU. Starting with the basics of Linux virtualization, you'll explore VM lifecycle management and migration techniques. You’ll then learn how to use SPICE and VNC protocols while creating VMs and discover best practices for using snapshots. As you progress, you'll integrate third-party tools with Ansible for automation and orchestration. You’ll also learn to scale out and monitor your environments, and will cover oVirt, OpenStack, Eucalyptus, AWS, and ELK stack. Throughout the book, you’ll find out more about tools such as Cloud-Init and Cloudbase-Init. Finally, you'll be taken through the performance tuning and troubleshooting guidelines for KVM-based virtual machines and a hypervisor. By the end of this book, you'll be well-versed with KVM virtualization and the tools and technologies needed to build and manage diverse virtualization environments.

Using the SPICE display protocol

Like KVM, a Simple Protocol for Independent Computing Environments (SPICE) is one of the best innovations that came into open source virtualization technologies. It propelled the open source virtualization to a large Virtual Desktop Infrastructure (VDI) implementation.

Important Note

Qumranet originally developed SPICE as a closed source code base in 2007. Red Hat, Inc. acquired Qumranet in 2008, and in December 2009, they decided to release the code under an open source license and treat the protocol as an open standard.

SPICE is the only open source solution available on Linux that gives two-way audio. It has high-quality 2D rendering capabilities that can make use of a client system's video card. SPICE also supports multiple HD monitors, encryption, smart card authentication, compression, and USB passthrough over the network.
