You can install Novell Cluster Services on a Xen virtualization host server (Dom0) running OES. You can create cluster resources that contain the virtual machine information by using the Xen and XenLive resource templates. You can fail over or cluster migrate these virtual machine cluster resources to different physical nodes in your cluster. Only the Xen and XenLive templates can be used in the Xen host server environment. You can modify these templates to work with other types of hypervisors.
All templates except Xen and XenLive are valid on guest servers (DomU). When Novell Cluster Services is installed on an OES guest server environment, no additional changes or special configuration are required. You can create clusters consisting of all virtual nodes, or use a combination of virtual and physical nodes.
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.
For information about why this configuration is necessary, see
TID 7004595: Novell Cluster Services is unable to detect a network link down when installed on a Xen domain 0 (dom0) on Novell Support.
