• Xen Cluster Management With Ganeti On Debian Lenny

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

  Xen Cluster Management With Ganeti On Debian Lenny Ganeti is a cluster virtualization management system based on Xen. In this tutorial I will explain how to create one virtual Xen machine (called an instance) on a cluster of two physical nodes, and how to manage and failover this instance between the two physical nodes.

• Xen Live Migration Of An LVM-Based Virtual Machine With iSCSI On Debian Lenny

  Author: Falko Timme • Tags: virtualization, debian, xen, storage • Comments: 11

  Xen Live Migration Of An LVM-Based Virtual Machine With iSCSI On Debian Lenny This guide explains how you can do a live migration of an LVM-based virtual machine (domU) from one Xen host to the other. I will use iSCSI to provide shared storage for the virtual machines in this tutorial. Both Xen hosts and the iSCSI target are running on Debian Lenny in this article.

• Installation And Setup Guide For DRBD, OpenAIS, Pacemaker + Xen On OpenSUSE 11.1

  Author: bhellman • Tags: high-availability, linux, suse, virtualization, xen • Comments: 4

  Installation And Setup Guide For DRBD, OpenAIS, Pacemaker + Xen On OpenSUSE 11.1 The following will install and configure DRBD, OpenAIS, Pacemaker and Xen on OpenSUSE 11.1 to provide highly-available virtual machines. This setup does not utilize Xen's live migration capabilities. Instead, VMs will be started on the secondary node as soon as failure of the primary is detected. Xen virtual disk images are replicated between nodes using DRBD and all services on the cluster will be managed by OpenAIS and Pacemaker. The following setup utilizes DRBD 8.3.2 and Pacemaker 1.0.4. It is important to note that DRBD 8.3.2 has come a long way since previous versions in terms of compatibility with Pacemaker. In particular, a new DRBD OCF resource agent script and new DRBD-level resource fencing features. This configuration will not work with older releases of DRBD.

• How To Enable Networking In Xen Guests On Hetzner's New EQ Servers (Debian Lenny)

  Author: Falko Timme • Tags: debian, virtualization, xen • Comments: 5

  How To Enable Networking In Xen Guests On Hetzner's New EQ Servers (Debian Lenny) This tutorial shows how you can enable networking in Xen guests (domU) on Hetzner's new EQ servers. With the new EQ servers, you can get up to three additional IPs that are in the same subnet as the server's main IP. The problem is that these additional IPs are bound to the MAC address of the host system (dom0) - Hetzner's routers will dump IP packets if they come from an unknown MAC address. This means we cannot use Xen's bridged mode, but must switch to Xen's routed mode where the host system (dom0) acts as the gateway for the guests.

• How To Enable Networking In Xen Guests On Hetzner's DS Servers (Debian Etch)

  Author: Falko Timme • Tags: debian, virtualization, xen • Comments: 4

  How To Enable Networking In Xen Guests On Hetzner's DS Servers (Debian Etch) This tutorial shows how you can enable networking in Xen guests (domU) on Hetzner's DS servers. With the DS servers, you can get a subnet of eight additional IPs (or more) - usually that subnet is different from the subnet that the server's main IP is from. The problem is that these additional IPs are bound to the MAC address of the host system (dom0) - Hetzner's routers will dump IP packets if they come from an unknown MAC address. This means we cannot use Xen's bridged mode, but must switch to Xen's routed mode where the host system (dom0) acts as the gateway for the guests.

• Paravirtualization With Xen On CentOS 5.4 (x86_64)

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

  Paravirtualization With Xen On CentOS 5.4 (x86_64) This tutorial provides step-by-step instructions on how to install Xen (version 3.0.3) on a CentOS 5.4 (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 (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.
