*** IF THIS PASSES QE ***
It is now supported to run the High Availability Add-On for Red Hat Enterprise Linux 6 within guests managed by Red Hat Enterprise Virtualization. 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.
