This is a known issue affecting vSphere 6.0 U2.
Currently, there is no resolution.
To work around this issue, unregister the vCloud Air Plugin com.vmware.vca if the vCloud Air Plugin is not in use.
To unregister the extension/plugin:
- Open the URL http://vCenter_Server_name_or_IP/mob through browser.
Note: Replace vCenter_Server_name_or_IP with actual vCenter Server name or IP address.
- Click Content.
- Click ExtensionManager.
- Select and copy the name of the plug-in you want to remove from the list of values under Properties. (Value is com.vmware.vca for the vCloud Air Plugin).
- Click UnregisterExtension. A new window appears.
- Paste the key of the plug-in.
- Click Invoke Method. This removes the plug-in and results in void.
- Close the window.
Note: Refresh the Managed Object Type:ManagedObjectReference:ExtensionManager window to verify the plug-in has been removed successfully.
