If i create a folder under hosts and clusters, and create a new data centre in this folder. When i then attempt to add a new host, i get an error message indicating
"there are not enough licenses installed to perform the operation"
Verify you have licensing for the VirtualCetner server, VC agents, and ESX server. On the last two you should have enough to cover all the physical CPUs. Are you using the license server for all your licensing?
