Problem

I'm trying to set up a virtual machine but I can't get it to do networking.

ServiceInstance si = new ServiceInstance(new URL(Url), user, password, true);
  VirtualMachine vm = (VirtualMachine) new InventoryNavigator(si.getRootFolder()).searchManagedEntity("VirtualMachine", "NewVmName");
  System.out.println( vm.getGuest().toolsRunningStatus);
  vm.getGuest().setIpAddress(ipAddress);

* Please tell me what to do to change the IP.

Solution

The IP address of a VM is controlled by the machine itself. Setting the IP address in the VM will not save. To set it you have to change it from Bridged to Internal. Here are some sources for this information: Superuser, OS Text
