##### SUMMARY
The following modules throw a `[WARNING]: Found internal 'results' key in module return, renamed to 'ansible_module_results'`:

* [ ]  `vmware_datastore_maintenancemode`
* [ ]  `vmware_host_kernel_manager`
* [ ]  `vmware_host_ntp`
* [ ]  `vmware_host_service_manager`
* [ ]  `vmware_tag`

I've generated the list like this:

`cd lib/ansible/modules/cloud/vmware/ && grep exit_json *.py | grep results= | cut -d ':' -f 1 | cut -d '.' -f 1`
