14.3 Virtual Machines as Cluster Nodes

In this scenario, you have OES 2 Linux (Xen) installed and configured on each node (physical machine). You then create either a NetWare or a Linux 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.

IMPORTANT:All virtual cluster nodes in the same cluster should be either Linux or NetWare. Do not mix Linux and NetWare cluster nodes in the same cluster.

You can then create and configure cluster resources on each virtual cluster node. 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 14-2 depicts using virtual machines as cluster nodes.
