I'm writing perl application about creating virtualNic in vCenter. Until now, the virtualNic is generated successfully and the mac-address can be retrieved, but I have to wait fourty-second for the ip-address returned. I want to know is there any efficient way to get ip-address immediately after generating the virtualNic? Or, if there is another way to allow me bind a newly-generated ip-address into the virtualNic? thank you for help.
