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)
