Install and setup Xen on Debian 4.0 Etch — Lone-Wolf Scripts

(via)
Xen is a GPLed virtualization solution available in Debian 4.0 Etch repositories. This article help you to create a coherent Xen installation, with backups and minimum security enhancements. This guide fits my vision of a Xen setup. If it does not fit yours, you are free to adapt it to your needs, or to not use it. For information In this guide, i use the term "virtual host". Be aware that Xen use its own terminology. In a Xen setup, instanciated (aka. started) virtual hosts are called "Domains". Once your computer configured for Xen, all the operating systems run in "domains". The original operating system, where the Xen's control tools are installed, is called "dom0" (for domain No zero). All the guest operating systems are said to be installed in a "domU" (for User domain). As i'm a little lazy (well, yeah... very lazy), i don't want to endure this mind twisting, and i will mainly use the "virtual host" term in this guide. So, if you read this guide, don't by angry at me because of the terms i use.

XEN Cluster HowTo

I have tried to run both Debian Etch and Ubuntu 8.04 Server on the cluster nodes, in Dom0. I started my tests with Debian, but I had some issues with slow samba performance in one VM that I couldn't fix so I decided to try Ubuntu Server, for the first time. Both installation went OK, the main difference was that I used mainly source code in Debian, but only packages in Ubuntu. I actually ran into more problems with Ubuntu due to some early bugs in the 8.04 release, will describe them below as I go along. And I have still to prove that running this setup in Ubuntu is stable.

quelques notes sur l'utilisation de l'hyperviseur Xen sur une dedibox avec une debian etch. Pour l'installation sur une dedibox v2 voir Xen dedibox2

Creating a local Debian mirror for your Xen servers - Shell Script (Bash) - xen, debian, etch, local mirror, amd64, anonftpsync, nginx

Once you’ve bought a dual or quad Xeon and started to experiment with virtualization you will soon want to create your local mirror to make installs lightning fast. This is a step-by-step how i did it.

Heartbeat2 Xen cluster with drbd8 and OCFS2

The idea behind the whole set-up is to get a High availability two node Cluster with redundant data. The two identical Servers are installed with Xen hypervisor and almost same configuration as Cluster nodes. The configuration and image files of Xen virtual machines are stored on drbd device for redundancy. Drbd8 and OCFS2 allows simultaneous mounting on both nodes, which is required for live migration of xen virtual machines. This Article describes Heartbeat2 Xen cluster Using Ubuntu (7.10) OS, drbd8 and OCFS2 (Ver. 1.39) File system. Although here Ubuntu is used it can be done in almost same way with Debian

Xen - 4gb seg fixup - Etch - Jonas Genannt

If you get this "4gb seg fixup" message on tty and/or in your /var/log/messages after the reboot to the Xen Hypervisor on Etch, you should check if you installed libc6-xen on your system. If not, install it, and reboot the system again.

Expérimentations avec Xen

Cette note présente une procédure d'installation de Xen en parallèle à NetBSD et Debian/Linux. L'objectif principal de la note est de décrire en détail une installation complète de Xen dans les deux environnements : d'autres documents existent sur la toile (voir les liens), mais ils pèchent par leur niveau de détail ou ils ne décrivent qu'une installation mono-OS. La note reste volontairement sur le côté pratique "recette de cuisine" pour l'installation. Xen est une technologie neuve, qui manque de poli. Les pièges rencontrés sur une installation sont encore nombreux (dûs par exemple aux différences subtiles entre les OS sur la définition d'une partition). Cette note vise à permettre à des non-spécialistes de NetBSD ou Debian de passer le cap de l'installation de Xen.

Howto: XEN on Debian "etch" [- LinuxFellaz.net - ]

This how-to provides step-by-step instructions on how to install Xen on an already working Debian Etch system. You can find all the software used here in the Etch repository, so no external files or compilation are needed.

Xen Live Migration with iSCSI

This is a document about how to set up XEN and iSCSI on 3 Debian Stable (3.1 / Sarge) machines so that you can have a virtual host that can be migrated live between 2 of the machines. The third machine will be the common disk for the virtual machine that is seen via the 2 machines running XEN. I have assumed you have some knowledge of Linux specifically Debian, but not limited to. You may need to solve some dependencies that I have left out by yourself. I can't think of everything, and I didn't start with completely empty machines.

setting up xen on your debian etch box | johnandcailin

there are many ways to setup xen, but i've put together a simple step-by-step guide to get a working xen system based on debian etch. easy as pie.

Nous verrons dans cet article comment installer Xen sur une machine n'ayant pas les instructions matérielles de virtualisation (VT) en utilisant LVM pour partitionner avec flexibilité nos différentes machines virtuelles. Le tout est réalisé grâce à Debian Etch avec les bons noyaux qui vont bien. J'ai aussi utilisé le noyau officiel de chez Xen afin d'avoir quelque chose de propre (enfin dans la limite du possible). Attention, mon tutoriel prends de véritables adresses IP, je n'ai donc aucun besoin de NAT. Si tel est votre problème, achetez le numéro 100 de GLMF, il contient le serveur parfait et un setup bien plus avancé que le miens :)

HA Xen Cluster with DRBD, LVM and heartbeat

We have implemented a 2-node HA Xen cluster, which consists of two physical machines (hosts,) and runs several virtual servers (guests) each, for our company's internal services (mail, web applications, development, etc.) When one host gets down unexpectedly, the other host physically kills it (STONITH - power down or reset) and then takes over all the guests the failed host was running. When we want to shutdown a host machine for maintenance (to replace a fan, add disk or memory, etc.), we just type the usual shutdown command, and the guests are automatically live-migrated to the other host. Since the guest servers keep running throughout the migration process, except for the less than a second pause, users would never even notice the event.

Xen Cluster Management With Ganeti On Debian Etch | HowtoForge - Linux Howtos and Tutorials

by 1 other
Ganeti is a cluster virtualization management system based on Xen. In this tutorial I will explain how to create one virtual Xen machine (called an instance) on a cluster of two physical nodes, and how to manage and failover this instance between the two physical nodes.

This tutorial explains how to convert a VMWARE image of a Debian Etch to a XEN image on a Debian Sid dom0 using XEN 3.0.3.

How To Make Your Xen-PAE Kernel Work With More Than 4GB RAM (Debian Etch With GRUB) | HowtoForge - Linux Howtos and Tutorials

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. I do not issue any guarantee that this will work for you!
