Virtualization With KVM On Ubuntu 9.04
This guide explains how you can install and use KVM for creating and running virtual machines on an Ubuntu 9.04 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.
Paravirtualization With Xen On CentOS 5.3 (x86_64)
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.
Install VMWareTools On Endian Firewall Community 2.2 RC3 (Released 07 October 2008) On ESXi (3.5)
This is a small guide that shows how to install VMware-Tools on Endian Firewall Community 2.2 RC3 (released 07 October 2008) on ESXi (3.5). I'm using Endian Firewall Community 2.2 RC3 (released 07 October 2008) on an ESXi 3.5 Server. Installing and using Endian is no problem but it's great to get VmwareTools installed.
How To Do Live Migration Of OpenVZ Containers
This guide explains how you can do a live migration of an OpenVZ container from one OpenVZ host to the other. Both OpenVZ hosts are running on Debian Lenny in this article, but the live migration does not differ on other distributions.
Creating A Fully Encrypted Para-Virtualised Xen Guest System Using Debian Lenny
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
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]
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.
KVM Virtualization With Enomalism 2 On A Fedora 10 Server
Enomalism ECP (Elastic Computing Platform) provides a web-based control panel that lets you design, deploy, and manage virtual machines on one or more host systems (in the case of multiple systems, we speak of a cluster or cloud). This article shows how you can use Enomalism (also know as Enomaly) to manage KVM guests on one Fedora 10 server.
Xen: How to Convert An Image-Based Guest To An LVM-Based Guest
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's often better to use LVM. Also, LVM-based guests are easier to back up (using LVM snapshots).
Virtualization With KVM On A CentOS 5.2 Server
This guide explains how you can install and use KVM for creating and running virtual machines on a CentOS 5.2 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.
