This time, it’s not a news about Xen Orchestra, but a benchmark of virtualization mode: PVHVM vs PV. When I saw the numbers from Rackspace, well… I choose to do my own tests here, despite it’s in other context (small test lab). We’ll (re)explain concepts first, then our test protocol and at least the results.

This tutorial provides step-by-step instructions on how to install Xen 4.0 on a Debian Squeeze (6.0) system (AMD64) and create paravirtualized guests (don’t mix this up with fully virtualized guests, i.e. hardware virtualization (HVM)).

This tutorial shows how to upgrade a Debian Lenny (Debian 5.0) installation on a Xen based Virtual Private Server (VPS) to Squeeze (Debian 6.0) including kernel update, dependency based boot sequencing and conversion to UUIDs.

Xen has had some interesting developments and the version in Lenny is just too old. Plus, the debian bootstrap scripts used to create images don’t support Ubuntu Maverick… Squeeze (testing) has the newest Xen and deboostrap, so that’s cool.

Xen is an opensource hypervisor. Version 4 has been released on the 7th of april 2010. Unfortunatly, Debian is only shipped with Xen version 3.2 for current stable Lenny, and version 3.4 for next stable Squeeze. Let’s see how to install Xen 4 on Lenny.
It sounds like a simple thing to do: As Ubuntu does not have support for Xen by default, I wanted to run a Debian Lenny Server as Xen host (Dom0) with Ubuntu Lucid (10.04) LTS as guest (DomU). But there were some obstacles
Ben Hutchings announced that the Debian kernel team are now building Xen flavoured kernels for Debian/Unstable . Thanks to Max Attems and the rest of the kernel team for this and all their other great work!

This should be an easy to follow guide about how to install Xen on Debian 5. You should be able to copy/paste most parts of on your shell. Please run this only on a clean and up-to-date Debian system.

Bastian Blank – which is the person (among others, but mainly him) that is packaging Xen in Debian -, has decided last summer that he doesn’t want to deal with the qemu-dm of Xen, thus removing Xen Qemu and support for HVM in Debian.

I’ve been using linux since about 1991 (I believe slackware was my first install) and decided to install Debian 5.0 (Lenny) and then install Xen server with Xfce4. To keep it light but useful.

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.
This guide explains how you can do a live migration of an LVM-based virtual machine (domU) from one Xen host to the other
After import: Debian boots, detects new hardware, and installs new device drivers. The boot sequence fails at the following error: ALERT! /dev/sda1 does not exist. Dropping to a shell!

I was running a Xen server with Debian Etch as dom0 (Linux 2.6.18-6 with Xen 3.0.3-1 on AMD64) for some time now. Today, I decided to upgrade the dom0 to Debian Lenny (Linux 2.6.26-2 with Xen 3.2.1-2).

This guide explains how you can set up fully-virtualized guests (HVM) with Xen 3.2 on a Debian Lenny x86_64 host system. HVM stands for HardwareVirtualMachine; to set up such guests, you need a CPU that supports hardware virtualization (Intel VT or AMD-V).

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.
