Paravirtualization With Xen On CentOS 5.6 (x86_64) This tutorial provides step-by-step instructions on how to install Xen (version 3.0.3) on a CentOS 5.6 (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, but still use the same hardware. in Public bookmarkswith centosdom0domuhypervisormachineparavirtualizationvirtualvirtualizationxen
