##### 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`
