Paravirtualization With Xen On CentOS 5.3 (x86_64)

Post date: May 17, 2009, 13:05 Category: Miscellaneous Views: 4490 Comments
Tutorial quote: This tutorial provides step-by-step instructions on how to install Xen (version 3.0.3) on a CentOS 5.3 (x86_64) system. Xen lets you create guest operating systems (*nix operating systems like Linux and FreeBSD), so called "virtual machines" or domUs, under a host operating system (dom0). Using Xen you can separate your applications into different virtual machines that are totally independent from each other (e.g. a virtual machine for a mail server, a virtual machine for a high-traffic web site, another virtual machine that serves your customers' web sites, a virtual machine for DNS, etc.), but still use the same hardware. This saves money, and what is even more important, it's more secure. If the virtual machine of your DNS server gets hacked, it has no effect on your other virtual machines. Plus, you can move virtual machines from one Xen server to the next one.

Creating A Fully Encrypted Para-Virtualised Xen Guest System Using Debian Lenny

Post date: May 3, 2009, 10:05 Category: Miscellaneous Views: 3186 Comments
Tutorial quote: This document explains how to set up a fully encrypted para-virtualized XEN instance. In this howto, the host system is running Debian Etch, while the guest system to be installed will be using Debian Lenny. If you are concerned about your privacy, you might want to consider using hard disk encryption to protect your valuable private data from spying eyes. Usually, the easiest way would be to use your distribution's installer to set up a fully encrypted system; I think most recent Linux distributions support this. However, when you are using XEN to provide virtualization, there are situations where you might not want to encrypt your whole computer with all guest instances, but instead only encrypt one OS instance. This howto will deal with exactly this situation. It assumes that the XEN host system is already up and running.

Xen Live Migration Of An LVM-Based Virtual Machine With iSCSI On Debian Lenny

Post date: April 30, 2009, 11:04 Category: Miscellaneous Views: 3818 Comments
Tutorial quote: This guide explains how you can do a live migration of an LVM-based virtual machine (domU) from one Xen host to the other. I will use iSCSI to provide shared storage for the virtual machines in this tutorial. Both Xen hosts and the iSCSI target are running on Debian Lenny in this article.

Managing Multiple KVM Hosts With Enomalism2 [Ubuntu 8.10]

Post date: April 23, 2009, 11:04 Category: Miscellaneous Views: 2533 Comments
Tutorial quote: In my previous guide about how to set up Enomalism2 on Ubuntu 8.10 I concentrated on just one KVM host. This tutorial is an extension to that article in that it shows how to add further Ubuntu 8.10 KVM hosts to the setup that can then be managed from one single control panel.

Xen: How to Convert An Image-Based Guest To An LVM-Based Guest

Post date: April 19, 2009, 10:04 Category: Miscellaneous Views: 2950 Comments
Tutorial quote: This short article explains how you can move/convert a Xen guest that uses disk images to LVM volumes. Virtual machines that use disk images are very slow and heavy on disk IO, therefore it is often better to use LVM. Also, LVM-based guests are easier to back up (using LVM snapshots).

VirtualBox 2: How To Pass Through USB Devices To Guests On An Ubuntu 8.10 Host

Post date: April 5, 2009, 12:04 Category: Miscellaneous Views: 3570 Comments
Tutorial quote: This short guide shows how you can pass through USB devices (such as a USB flash drive) to VirtualBox guests on an Ubuntu 8.10 VirtualBox 2 host. USB support is available only in the VirtualBox PUEL (closed-source) edition, not in the OSE edition, so make sure you have the PUEL edition installed.

A Short Introduction To Apt-Pinning

Post date: March 24, 2009, 12:03 Category: Miscellaneous Views: 2953 Comments
Tutorial quote: This article is a short overview of how to use apt-pinning on Debian and Debian-based distributions (like Ubuntu). Apt-Pinning allows you to use multiple releases (e.g. stable, testing, and unstable) on your system and to specify when to install a package from which release. That way you can run a system based mostly on the stable release, but also install some newer packages from testing or unstable (or third-party repositories).

Virtualization With KVM On A Fedora 10 Server

Post date: March 22, 2009, 13:03 Category: Miscellaneous Views: 2742 Comments
Tutorial quote: This guide explains how you can install and use KVM for creating and running virtual machines on a Fedora 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. Intel VT or AMD-V.

Installing KVM Guests With virt-install On Ubuntu 8.10 Server

Post date: March 10, 2009, 12:03 Category: Miscellaneous Views: 3877 Comments
Tutorial quote: Unlike virt-manager, virt-install is a command line tool that allows you to create KVM guests on a headless server. You may ask yourself: "But I can use vmbuilder to do this, why do I need virt-install?" The difference between virt-install and vmbuilder is that vmbuilder is for creating Ubuntu-based guests, whereas virt-install lets you install all kinds of operating systems (e.g. Linux, Windows, Solaris, FreeBSD, OpenBSD) and distributions in a guest, just like virt-manager. This article shows how you can use it on an Ubuntu 8.10 KVM server.

Installing Windows XP As A KVM Guest On Ubuntu 8.10 Desktop

Post date: February 15, 2009, 12:02 Category: Miscellaneous Views: 4213 Comments
Tutorial quote: There's a bug in virt-install and virt-manager on Ubuntu 8.10 that does not let you run Windows XP as a guest under KVM. During the Windows installation, the guest needs to be rebooted, and then you get the following error, and Windows XP refuses to boot: "A disk read error occured. Press Ctrl+Alt+Del to restart". This guide shows how you can solve the problem and install Windows XP as a KVM guest on Ubuntu 8.10.
