Interactively installing Debian virtual machines with virt-install without having to download anything in advance can already be done by pointing it to a Debian mirror via –location. But you can also add files to the initrd after downloading using –initrd-inject.

This guide explains how you can create advanced virtual hosts on a lighttpd web server on Debian Squeeze that are stored in a MySQL database. The method described here does not use the lighttpd mod_mysql_vhost module, and unlike mod_mysql_vhost (which allows you to store only the hostname and document root of a vhost in a [...]

This guide explains how you can use mod_mysql_vhost to create simple virtual hosts on a lighttpd web server on Debian Squeeze. With mod_mysql_vhost, lighttpd can read the vhost configuration from a MySQL database. Currently, you can store the domain and the document root in the MySQL database which results in very simple virtual hosts. If [...]

A few months back, I posted an article about setting up a small home server. I’ve been playing around with the setup of that machine lately, and rather than breaking the working system, I’ve been perfecting my setup in a virtualized environment.

In this article, you will learn what is virtualization, why use it and how to use one kind of virtualization, Linux containers (aka lxc) under Debian Squeeze.

This tutorial explains how to create an OpenVZ template for Debian Wheezy (Debian Testing) that you can use to create virtual Debian Wheezy machines under OpenVZ. I searched for a Debian Wheezy OpenVZ template, but couldn’t find one, that’s why I decided to create it myself. This guide can also be used for creating Debian [...]

I’m using this QEMU image to do compile-tests on the PowerPC architecture for various software projects, especially flashrom (open-source flash ROM programming software). So here’s how to install Debian GNU/Linux on PowerPC (in QEMU)

The XCP team would like to formally announce Project Kronos, our port of XCP’s XenAPI toolstack to Debian and Ubuntu dom0. This will give users the ability to install Debian or Ubuntu, and then just do ‘apt-get install xapi’ in order to build a system that is (roughly) functionally equivalent to a standard XCP distribution

Have you tried VirtualBox 4.1 yet? I hope it isn’t because the latest packaged version for your OS is 4.0.12 and you feel as if you’re stuck there. You’re not stuck there. This short tutorial will guide you through the installation. This installation is for Debian-related Linux distributions.

Microsoft says that its Hyper-V virtualization stack may soon support the Ubuntu and Debian Linux distros as well as CentOS, Red Hat, and SuSE.

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 create a Debian Squeeze (6.0) domU on dom0 running CentOS 5.5 x86_64.

This guide explains how you can install and use KVM for creating and running virtual machines on a Debian Squeeze server. I will show how to create image-based virtual machines and also virtual machines that use a logical volume (LVM).

VirtualBox OSE is a very easy-to-use virtualization tool. It has a GUI interface and installation wizards to help you through the process, so it really doesn’t feel like you’re doing anything as complicated as setting up a virtual host system on your computer.

I downloaded deb of VirtualBox beta 1 from the beta packages page of Oracle website and installed it. However, while launching Virtual Machines created with Oracle VirtualBox 3.x (closed source version), I got the following error

This tutorial shows how you can install Sun xVM VirtualBox 2 on a Debian Lenny desktop. VirtualBox is available as a package from the official Debian Lenny repository, but it’s very old (version 1.6.6), therefore I explain how to install the current version (2.1.4 at the time of this writing).

In my current Drupal development environment, I run an entire Debian server stack (LAMP + Memcache + Varnish, etc) inside of a VirtualBox virtual machine. On those frustration-laden occasions when I need to fire up the debugger, I use MacGDBp to connect to the virtual machine.

In the past week I’ve been doing some work on the MongoDB PHP Driver, and while running the test cases I noticed that there are some issues with it when you run out of disk space. It’s sadly hard to reproduce so I set out to create a VMWare image for the MongoDB developers to [...]

The first part of this tutorial, you hopefully need to do only once: creating a fresh Debian system. In the second part we will build on this image to create many different servers.

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

I am determined to try out CouchDB 0.11. Since I don’t want to muck with the nice dev environment that I have going I will install that onto a VM. So I fire up VirtualBox and create a new VM:

After a fresh installation of Debian Lenny, I wanted to use a quite very recent version of VirtualBox. One solution is the Debian backports : Here are the VirtualBox packages available

Yesterday I played with QEMU in order to run a Debian Lenny distro on a virtualized ARM arch. The Debian installation was easy thanks to this post of Chris Dew. I just wanted to point out what I did to get the virtual machine running after installing the distro.

Have you ever wanted to develop your web application locally. Using VirtualBox you can develop with a near clone of your production environment. Giving you a personal sandbox where you can go crazy before you commit to your teams development server.

I’ve been encountering an interesting issue recently with Debian running as a guest in side of VirtualBox on Windows XP. When I initially installed Debian, I told it to adjust the hardware clock to UTC.

A new release of VirtualBox is available in the Debian testing repositories. If already installed on your system, it will be automatically upgraded if you are using Debian testing.

I warned that if the virtualization layer enforces the use of encapsulation boundaries that interfere with that abstraction, then virtualization becomes less useful. I put forward the use of a software iSCSI initiator on Debian under XenServer as a case in point.

There are a few methods of running virtual machines on a Linux host: VirtualBox, VMWare, KVM, and QEMU are four of the most popular. Each method has it’s pros and cons.

I realize it is pretty straight forward but I think it might help other who are having trouble. VirtualBox is still not perfect in the linux guest arena but its gotten a lot better over the past year since Sun apparently threw a bunch of money into it.
