We run VirtualCenter 2.5 Update 5 (Build 147633). We only have 1 ESX host added to vCenter. In licensed features - under Add-Ons, it shows we are licensed for 2 CPUs for VMware DRS, VirtualCenter Agent for ESX Server, and VMotion. VMware Consolidated Backup and VMware HA both show as "Not Used." My question is, when I click edit, all of these features are listed with check marks, except for VMware Consolidated Backup - which has an empty box with no check mark. It allows me to check that box, however once I do so, and then restart the License Server service, VirtualCenter Agent for ESX Server then shows as "Unregistered Version". If I revert back - all is well. We do own a license for VI3 Enterprise, as well as VMware vCenter Server 2. Does that not include VMware Consolidated Backup??
