    Author: Falko Timme • Tags: , , • Comments: 4

    Installing And Using OpenVZ On CentOS 5.2 In this HowTo I will describe how to prepare a CentOS 5.2 server for OpenVZ. With OpenVZ you can create multiple Virtual Private Servers (VPS) on the same hardware, similar to Xen and the Linux Vserver project. OpenVZ is the open-source branch of Virtuozzo, a commercial virtualization solution used by many providers that offer virtual servers. The OpenVZ kernel patch is licensed under the GPL license, and the user-level tools are under the QPL license.

    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.

  • Installing Xen On CentOS 5.2 (i386)

    xen Author: Falko Timme • Tags: , , • Comments: 9

    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.
