Creating A Xen Virtual Machine Cluster Resource - Novell OPEN ENTERPRISE SERVER 2 SP 2 - CLUSTER SERVICES 1.8.7 FOR LINUX Manual

12.2.1 Creating a Xen Virtual Machine Cluster Resource

Novell Cluster Services includes two Xen (virtual machine) resource templates, which greatly
simplify the process for creating a virtual machine cluster resource. Much of the virtual machine
cluster resource configuration is performed automatically by the Xen resource templates. The two
templates are named Xen_Template and XenLive_Template. Both templates perform similar
functions to automatically configure the cluster resource for the virtual machine.
The XenLive template provides an additional function to allow a manual virtual machine resource
migration without the need to boot or bring up the virtual machine on the cluster node where the
virtual machine has been migrated. This lets clients continue to access a virtual machine that has
been migrated without reconnecting or waiting for the virtual machine to boot or load on the target
node.
IMPORTANT: The live migrate function is only useful for a manual virtual machine resource
migration, and does not work for a virtual machine resource failover or failback.
Make sure that your Xen setup is working properly before you attempt to set up the Novell Cluster
Services clustering for your virtual machines in the Xen host environment. Refer to the
Virtualization with Xen (http://www.novell.com/documentation/sles10/book_virtualization_xen/
data/book_virtualization_xen.html)
To configure a virtual machine as a cluster resource:
1 Open your Internet browser and enter the URL for iManager.
The URL is http://server_ip_address/nps/imanager.html. Replace server_ip_address with the
IP address or DNS name of a server in the cluster or with the IP address for Apache-based
services.
2 Specify your username and password, specify the tree where you are installing the cluster, then
click Login.
3 In iManager, select Clusters, then click Cluster Options.
Under Clusters, iManager displays four links that you can use to configure and manage your
cluster.
4 Browse and select the cluster name.
5 On the Cluster Options page, click New.
6 Click the Resource radio button to specify Resource as the resource type you want to create,
then click Next.
7 Specify a name for the virtual machine resource.
8 In the Inherit From Template field, browse to the Cluster object container, then select the
desired Xen template name from the list of templates in the container.
The Xen templates are named Xen_Template and XenLive_Template.
9 Select the Define Additional Properties check box, click Next, then continue with
Virtual Machine Load, Unload, and Monitor Scripts" on page
to find out how to set up XEN and XEN virtual machines.
