To switch to using Admin Console instead of the Infrastructure Manager (IM), please refer to the following url:
You must -> Enable bulk configuration.
Using the Admin Console portlet (AC) -- is not compatible with configuration through the Infrastructure Manager interface. Do not mix or interchange configuration methods! If you do, the result will be unpredictable monitoring of your VMware hosts and/or VMs and/or corruption of your vmware configuration.
When you enable bulk configuration, Infrastructure Manager is disabled and the Template Editor appears in the Admin Console GUI.
Once you enable bulk configuration, there is no supported process for going back to manual configuration. Be sure that you fully understand and accept the consequences of enabling bulk configuration before enabling it.
