Virtual Machines As Cluster Nodes - Novell OPEN ENTERPRISE SERVER 2 SP 2 - CLUSTER SERVICES 1.8.7 FOR LINUX Manual

Make sure that your OCFS2 file system is working properly before you attempt to use it with
Novell Cluster Services.
An overview of OCFS2 is available in
documentation/sles10/sles_admin/data/cha_ocfs2.html)
10 SP2 Administration Guide. For detailed information about using OCFS2, see the
Project (http://oss.oracle.com/projects/ocfs2/)
For information about setting up live migration, see

12.3 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.
