• Virtualization With Xen On CentOS 6.2 (x86_64) (Paravirtualization & Hardware Virtualization)

  Author: Falko Timme • Tags: centos, virtualization, xen • Comments: 11

  Virtualization With Xen On CentOS 6.2 (x86_64) (Paravirtualization & Hardware Virtualization) This tutorial provides step-by-step instructions on how to install Xen (version 4.1.2) on a CentOS 6.2 (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.

  Author: Falko Timme • Tags: kvm, ubuntu, virtualization • Comments: 1

  Installing KVM Guests With virt-install On Ubuntu 12.04 LTS Server Unlike virt-manager, virt-install is a command line tool that allows you to create KVM guests on a headless server.
