The Linux kernel supports a variety of virtualization schemes, and that's likely to grow as virtualization advances and new schemes are discovered (for example, lguest). But with all these virtualization schemes running on top of Linux, how do they exploit the underlying kernel for I/O virtualization?

Virtualization is the latest buzz word. You may wonder computers are getting cheaper every day, why should I care and why should I use virtualization? Virtualization is a broad term that refers to the abstraction of computer resources such as...

Virtualization has become an important aspect of the functionality of todays computers and computer Operating Systems. Many that are new to Linux or new to Virtualization often are overwhelmed by the number of Virtualization options the Linux Desktop has and often ask: "What Virtualization Solution is best suited for my needs".

One of the areas in which open-source software has truly come into its own during the last few years is virtualization.  The latest LTS release of Ubuntu, which offers a variety of Free virtualization solutions, makes this abundantly clear.  Below, we take a look at some of those options, with a focus on KVM, and consider their meaning for Ubuntu users.

Kernel-based Virtual Machine (KVM) is a Linux kernel virtualization infrastructure. KVM is a full virtualization solution for Linux on x86 hardware containing virtualization extensions Intel VT (vmx) or AMD-V (svm).

Despite Red Hat’s surprising announcement last week that it would be partnering with Microsoft on virtualization, on February 23rd, Red Hat’s announced that it would be switching its virtualization strategy from a mix of virtualization programs, including the Microsoft-friendly Xen, to focusing on Linux’s baked-in KVM (Kernel-based Virtual Machine)

This guide explains how you can install and use KVM for creating and running virtual machines on an Ubuntu 12.10 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.

This guide explains how you can install and use KVM for creating and running virtual machines on an Ubuntu 12.04 LTS 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.
