15.3 Virtual Machines as Cluster Nodes

In this scenario, you have OES 11x and Xen installed and configured on each node (physical machine). You create the OES virtual machine on each physical machine and install and configure Novell Cluster Services on each virtual machine. The combined virtual machines (cluster nodes) comprise one cluster.

You can then create and configure cluster resources that run on the virtual cluster nodes. The process for creating and configuring cluster resources on a virtual cluster node is the same as on a physical cluster node.

Cluster resources can be failed over or migrated between virtual cluster nodes that are on the same physical node or on separate physical nodes.

Figure 15-2 depicts using virtual machines as cluster nodes.
