There are two caveats: + +1) The guests must use SCSI-based fencing in conjunction with iSCSI storage; no other storage or fencing model is supported at this time. +2) The cluster configuration must use UDP Unicast (UDPU) for network transport. UDPU is technical preview. To enable the UDPU transport, manually add the line <cman transport="udpu"/> to the cluster.conf file. Please note that because of BZ#695795, it is not possible to override totem defaults with the totem tag. A complete cluster restart is required when making this change. The udpu transport is not on-wire compatible with the default multicast transport.
