I have seen this error message when the VM within vCenter is not connected to a proper VM Port Group or you'll get that error. As a result I my PowerCLI script I use to import VM's from vCenter into VCD checks for this.
I have also seen this when the hardware version of the VM is below version 7.
Check both of these and let me know if it is still an issue.
