Installing Xen On CentOS 5.2 (i386)

Installing Xen On CentOS 5.2 (i386)

This tutorial provides step-by-step instructions on how to install Xen (version 3.0.3) on a CentOS 5.2 system (i386). 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.

Virtualization With XenServer Express 5.0.0

Virtualization With XenServer Express 5.0.0

This Howto covers the installation of XenServer Express 5.0.0 and the creation of virtual machines with the XenCenter administrator console. XenServer Express is the free virtualization platform from Citrix, the company behind the well known Xen virtualization engine. XenServer Express makes it easy to create, run and manage Xen virtual machines with the XenCenter administrator console. The XenServer Express installation CD contains a full Linux distribution which is customized to run XenServer Express.

The Perfect Load-Balanced & High-Availability Web Cluster With 2 Servers Running Xen On Ubuntu 8.04 Hardy Heron

The Perfect Load-Balanced & High-Availability Web Cluster With 2 Servers Running Xen On Ubuntu 8.04 Hardy Heron

In this howto we will build a load-balanced and high-availability web cluster on 2 real servers with Xen, hearbeat and ldirectord. The cluster will do http, mail, DNS, MySQL database and will be completely monitored. This is currently used on a production server with a couple of websites. The goal of this tutorial is to achieve load balancing & high availability with as few real servers as possible and of course, with open-source software. More servers means more hardware & hosting cost.

Create CentOS 5.2 Domu on Ubuntu Hardy Dom0

Create CentOS 5.2 Domu on Ubuntu Hardy Dom0

This tutorial provides step-by-step instructions on how to install Images of xen on an Ubuntu Hardy Heron (Ubuntu 8.04) server system (i386). Linux distributions that can run as Xen guests out of the box, obviating the need to create your own custom filesystems. The filesystems on jailtime.org have already been tweaked to deal with Xen’s idiosyncracies, and are also designed to be lightweight and minimally divergent from the original distribution.

How To Create A Cluster Testbed Using CentOS 5 Virtualization And iSCSI

How To Create A Cluster Testbed Using CentOS 5 Virtualization And iSCSI

This guide attempts to provide a Xen based test environment where you can practice setting up a two node cluster (cluster setup itself is not discussed here - I'm merely giving you what you need to set it up).

How To Make Your Xen-PAE Kernel Work With More Than 4GB RAM (Debian Etch With GRUB)

How To Make Your Xen-PAE Kernel Work With More Than 4GB RAM (Debian Etch With GRUB)

If you have a server with more than 4GB RAM and want to install a 32bit Debian Etch on it (following this tutorial: Debian Etch And Xen From The Debian Repository), you'd expect the Xen-PAE kernel to see all your RAM because the Xen-PAE kernel supports up to 64GB RAM. In fact, it recognizes only about 3.3GB RAM due to a bug in the GRUB bootloader. This article explains how you can fix GRUB so that all your RAM gets recognized.

Xen With Graphical User Interface On A Fedora 7 Desktop

Xen With Graphical User Interface On A Fedora 7 Desktop

This document describes how to set up Xen on Fedora 7. Xen enables the paravirtualization of your hardware for its virtual machines if you have a CPU with Vanderpool (Intel) or Pacifica (AMD) technology. The paravirtualization provides high performance to your virtual machines. Fedora's virt-manager provides an easy to use GUI for setting up and managing your virtual machines. It does not have the extensive features like VMware Server, but the basics are in place.
