A number of new options are available when creating a new cluster, such as the new fencing tab, and the ability to set a maintenance reason for virtual machines.
The maintenance reason feature is described as follows -
"RHEV admin teams would benefit from a mechanism that asks for an optional reason when performing administrative actions on VMs: when a VM is shutdown/powered off from the mananger there's an optional "reason" field where the administrator can write a free-form explanation for the maintenance, which would be bought to attention in the logs and when/if someone attempts to power on."
This bug entails updating section 5.2 of the Administration Guide to include new options in the existing channels and add new tables to document any new tabs in the New Cluster window.
