Overview of this book

A robust datacenter is essential for any organization – but you don’t want to waste resources. With KVM you can virtualize your datacenter, transforming a Linux operating system into a powerful hypervisor that allows you to manage multiple OS with minimal fuss. This book doesn’t just show you how to virtualize with KVM – it shows you how to do it well. Written to make you an expert on KVM, you’ll learn to manage the three essential pillars of scalability, performance and security – as well as some useful integrations with cloud services such as OpenStack. From the fundamentals of setting up a standalone KVM virtualization platform, and the best tools to harness it effectively, including virt-manager, and kimchi-project, everything you do is built around making KVM work for you in the real-world, helping you to interact and customize it as you need it. With further guidance on performance optimization for Microsoft Windows and RHEL virtual machines, as well as proven strategies for backup and disaster recovery, you’ll can be confident that your virtualized data center is working for your organization – not hampering it. Finally, the book will empower you to unlock the full potential of cloud through KVM. Migrating your physical machines to the cloud can be challenging, but once you’ve mastered KVM, it’s a little easie.

Why should I use Linux virtualization?

Virtualization first appeared in Linux in the form of User-mode Linux (UML) and it started the revolution required to bring Linux into the virtualization race. Today, there is a wide array of virtualization options available in Linux to convert a single computer into multiple ones. Popular Linux virtualization solutions include KVM, Xen, QEMU, and VirtualBox. In this book, we will be focusing on KVM virtualization.

Openness, flexibility, and performance are some of the major factors that attract users to Linux virtualization. Just like any other open source software, virtualization software in Linux is developed in a collaborative manner; this indirectly brings users the advantages of the open source model. For example, compared to closed source, open source receives wider input from the community and indirectly helps reduce research and development costs, improves efficiency, and performance and productivity. The open source model always encourages innovation. The following are some of the other features that open source provides:

  • User-driven solutions for real problems
  • Support from the community and a user base who help fellow users to solve problems
  • Provides choice of infrastructure
  • Control of data and security, as the code is freely available to read, understand, and modify when required
  • Avoid lock-in flexibility to migrate the entire load with comparable product and stay free from vendor lock-in
