hello daphnissov,  

Deeply  appreciate your  attention  and  messages. It seems  impossible for  me  to  restart  vmware tools  in  my  application.  I  am  trying  the other  way  to  assign  the  ipaddress into  the  newly  created  virtualNic.  Currently,  I  find  the  solution of using  CustomizationVM_Task  to implement  this requirement.  According to documentation, CustomizationSpec  is  needed  for  this  task,  and  three  arguments  nicSettingMap, identity  and globalIPSettings are needed.  right now,  the  parameter globalIPSettings  is  undetermined. To build a globalIPSettings  variable,  it is supposed  to  use  two xsd:string[]  parameters: dnsServerList &  dnsSuffixList. I tested by  using  arrayofstring in several different  formats, but  always  get  syntax errors.
