The OpenVZ kernel patch is licensed under the GPL license, and the user-level tools are under the QPL license.

Installing Xen On CentOS 5.2 (i386)

Thu, 06 Nov 2008 18:57:04 +0100

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.

How To Set Up A Cisco Lab On Linux (CentOS 5.2)

How To Set Up A Cisco Lab On Linux (CentOS 5.2)

I recently decided to study for the Cisco CCSP certification. My main concern in the beginning was the fact that most of the lab simulation software that I found out there could only run on Windows, this was a problem for me given the fact that I do not own a windows computer. After a quick search I found the wonderful Dynamips project that goes beyond what other simulators do by running actual Cisco IOS images, as well as the PEMU project which allows for running of Cisco PIX images. To integrate the various pieces of software and provide an interface for interaction with the devices I used dynagen.
