Turn Your Ubuntu Server into a Virtualization Host with KVM

Unlock the Power of Multiple Servers on One Machine

Virtualization is a cornerstone of modern IT, and the ‘Ubuntu System Administration Guide’ shows you how to transform a standard Ubuntu server into a powerful host for running multiple virtual machines (VMs). The guide focuses on KVM (Kernel-based Virtual Machine), the native virtualization solution for Linux.

Why Host VMs on Your Server?

Running VMs allows you to isolate services, test new software in a safe environment, and make efficient use of your hardware. Instead of needing a separate physical machine for every service, you can run them all on a single, powerful server, each within its own secure and independent virtual environment.

Getting Started with KVM

The first step is to ensure your server’s CPU has virtualization support enabled in the BIOS. The book then guides you through installing all the necessary KVM packages with a single `apt` command. Once installed, you can verify that KVM acceleration is available with the `kvm-ok` command, confirming your server is ready to host VMs.
