Setting the Property of HostName and VirtualMachine.NetworkN.DNSSuffix not setting the FQDN on vcenter Machine

Hi,

We are setting the Hostname and  VirtualMachine.Network0.DNSSuffix  from a VCO workflow by extending the WFStubBuildingMachine. The hostname is set but the DNSSuffix is not getting appended to become a FQDN on vcenter vm.

Are we missing any step in process of setting a FQDN for a virtual machine programitcally using VCO.

We do not want to use VCAC Network profiles as we integrating with an external IPAM solution which provides us a Hostname and its DNSSuffix

Regards
