servers) by using the same methods and processes as those used on a physical server. No additional
changes or special configuration are required.
You can install Novell Cluster Services on the virtualization host server and create cluster resources
that contain the virtual machines. You can fail over or migrate virtual machine cluster resources
(entire virtual machines) to different physical nodes in your cluster. Resource templates are provided
for Xen* virtualization environments.
IMPORTANT: All templates except Xen and XenLive are valid in guest servers (DomU) in the
virtualization environment. Only the Xen and XenLive templates can be used in the OES 2 Linux
(Xen) host environment (that is, in Dom0, but not in DomU).
Although many different cluster virtualization scenarios are possible, only those outlined in the
sections below have been tested:
Section 12.1, "Prerequisites for Xen Host Server Environments," on page 181
Section 12.2, "Virtual Machines as Cluster Resources," on page 182
Section 12.3, "Virtual Machines as Cluster Nodes," on page 190
Section 12.4, "Virtual Cluster Nodes in Separate Clusters," on page 191

12.1 Prerequisites for Xen Host Server
Environments
When using Novell Cluster Services to create cluster resources in a Xen host server environment,
one network adapter on each cluster node must be available without Xen bridging to allow Novell
Cluster Services to monitor for network state changes in the cluster. You need at least one other
network adapter on each cluster node to use as a bridge for the virtual servers that will be hosted on
the Xen host.
For each cluster node, determine which network adapter you want to use for Novell Cluster Services
communications and network state monitoring, then do the following:
Disable bridging on the network adapter.
Assign the IP address of the host server to the network adapter.
