• How To Make Your Xen-PAE Kernel Work With More Than 4GB RAM (Debian Etch With GRUB)

  Author: Falko Timme • Tags: debian, virtualization, xen • Comments: 1

  How To Make Your Xen-PAE Kernel Work With More Than 4GB RAM (Debian Etch With GRUB) If you have a server with more than 4GB RAM and want to install a 32bit Debian Etch on it (following this tutorial: Debian Etch And Xen From The Debian Repository), you'd expect the Xen-PAE kernel to see all your RAM because the Xen-PAE kernel supports up to 64GB RAM. In fact, it recognizes only about 3.3GB RAM due to a bug in the GRUB bootloader. This article explains how you can fix GRUB so that all your RAM gets recognized.

  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.

• The Perfect Load-Balanced & High-Availability Web Cluster With 2 Servers Running Xen On Ubuntu 8.04 Hardy Heron

  Author: marchost • Tags: virtualization, ubuntu, high-availability, xen • Comments: 2

  The Perfect Load-Balanced & High-Availability Web Cluster With 2 Servers Running Xen On Ubuntu 8.04 Hardy Heron In this howto we will build a load-balanced and high-availability web cluster on 2 real servers with Xen, hearbeat and ldirectord. The cluster will do http, mail, DNS, MySQL database and will be completely monitored. This is currently used on a production server with a couple of websites. The goal of this tutorial is to achieve load balancing & high availability with as few real servers as possible and of course, with open-source software. More servers means more hardware & hosting cost.

• Installing Xen On CentOS 5.2 (i386)

  Author: Falko Timme • Tags: centos, virtualization, xen • 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.

• Creating Virtual Machines For Xen, KVM, VMware Workstation 6, and VMware Server With vmbuilder On Ubuntu 8.10

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

  Creating Virtual Machines For Xen, KVM, VMware Workstation 6, and VMware Server With vmbuilder On Ubuntu 8.10 vmbuilder is a tool (introduced on Ubuntu 8.10) that allows you to build virtual machines (with Ubuntu as the OS) for multiple virtualization techniques. Currently it supports Xen, KVM, VMware Workstation 6, and VMware Server. You can afterwards copy the virtual machines to another system (a Xen, KVM, VMware Workstation 6, or VMware Server host) and run them there.

• Using Xen With LVM-Based VMs Instead Of Image-Based VMs (Debian Etch)

  Author: Falko Timme • Tags: debian, virtualization, xen • Comments: 2

  Using Xen With LVM-Based VMs Instead Of Image-Based VMs (Debian Etch) This guide explains how you can set up LVM-based virtual machines on a Xen host running on Debian Etch instead of virtual machines that use disk images. Virtual machines that use disk images are very slow and heavy on disk IO.

• How To Convert Physical Systems And Xen VMs Into OpenVZ Containers (Debian Etch)

  Author: Falko Timme • Tags: debian, openvz, virtualization, xen • Comments: 10

  How To Convert Physical Systems And Xen VMs Into OpenVZ Containers (Debian Etch) This guide explains how you can convert physical systems (running Debian Etch) or Xen domUs (also running Debian Etch) into an OpenVZ container. This procedure should also work for converting VMware VMs, VirtualBox VMs, or KVM VMs into OpenVZ containers, but I haven't tried this. It should work for other Linux distributions as well, with minor modifications (for example, the network configuration is not located in /etc/network/interfaces if you're not on Debian/Ubuntu).
