pyVmomi - failed adding VirtualAHCIController when deploying a newly-configured VM

[jimin18]

Creating VM using vim.vm.ConfigSpec, adding SCSI, SATA controller through VirtualDeviceSpec, SCSI and Disk are able to get created, but AHCI controller and CDRom could not be added.

Following is the script, can anybody help to share some experience. Thanks in advance.
