We're going to deliberately sidestep the jargon and the hype to take a practical look at the virtualisation technologies in Ubuntu, in particular KVM and Qemu and the related userspace tools that create and manage virtual machines. Although the discussion centres on Ubuntu, the technology is applicable to all Linux distros.

This guide explans how you can install and use KVM for creating and running virtual machines on an Ubuntu 9.10 server. I will show how to create image-based virtual machines and also virtual machines that use a logical volume (LVM). KVM is short for Kernel-based Virtual Machine and makes use of hardware virtualization, i.e., you need a CPU that supports hardware virtualization, e.g.

Red Hat's KVM virtualization technology is so advanced that it will inevitably consign the Xen hypervisor to the technological scrap heap.

Red Hat today officially announced the beta availability of Red Hat Enterprise Linux 5.4 (RHEL), which in my view is a lot more than a typical point release. Sure we're all waiting for the big RHEL 6 release, but there are some major changes in RHEL 5.4.

This guide explains how you can install and use KVM for creating and running virtual machines on a CentOS 5.2 server. I will show how to create image-based virtual machines and also virtual machines that use a logical volume (LVM).
