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.

Chapter 10: Automated Windows Guest Deployment and Customization

Now that we have covered the different ways of deploying Linux-based Virtual Machines (VMs) in KVM, it's time to switch our focus to Microsoft Windows. Specifically, we'll work on Windows Server 2019 machines running on KVM, and cover prerequisites and different scenarios for the deployment and customization of Windows Server 2019 VMs. This book isn't based on the idea of Virtual desktop infrastructure (VDI) and desktop operating systems, which require a completely different scenario, approach, and technical implementation than virtualizing server operating systems.

In this chapter, we will cover the following topics:

  • The prerequisites to creating Windows VMs on KVM
  • Creating Windows VMs using the virt-install utility
  • The customization of Windows VMs using cloudbase-init
  • cloudbase-init customization examples
  • Troubleshooting common cloudbase-init customization issues
