In this scenario, you have OES 11x and Xen installed and configured on each node (physical machine). You create multiple OES virtual machines on each physical machine and install and configure Novell Cluster Services on each virtual machine. During the Novell Cluster Services installation, you create separate clusters of virtual cluster nodes, with each virtual cluster node residing on a separate physical machine. This way you have multiple clusters of virtual cluster nodes on fewer physical machines.
You can then create and configure cluster resources on each virtual cluster node and cluster. The process for creating and configuring cluster resources on a virtual cluster node is the same as on a physical cluster node.
Figure 15-3 depicts using virtual cluster nodes in separate clusters.
