This is what i ended up with. I wanted to change the network of my VMs with a single NIC at provisioning on my distributed virtual switch. This has vm as VC:VirtualMachine and network as string as inputs.
var spec = new VcVirtualMachineConfigSpec(); // Initialize a Virtual Machine Config Spec first
var myDeviceChange = new Array(); // Create an array to hold all of your changes
var devices = vm.config.hardware.device;
var pgs = VcPlugin.getAllDistributedVirtualPortgroups();
for each (pg in pgs) {
if (pg.name.indexOf(network) > -1) {
portGroup = pg;
System.log("Found Portgroup: " + portGroup.name);
}
}
//Find devices that are VMXNET3 or E1000
for (var i in devices)
{
if (
(devices[i] instanceof VcVirtualVmxnet3) ||
(devices[i] instanceof VcVirtualE1000)
)
{
System.log("The device we are going to modify is: " + devices[i]);
var nicSpec = new VcVirtualDeviceConfigSpec();
nicSpec.operation = VcVirtualDeviceConfigSpecOperation.edit;
nicSpec.device = new VcVirtualVmxnet3();
nicSpec.device.key = devices[i].key;
nicSpec.device.deviceInfo = new VcDescription();
nicSpec.device.deviceInfo.label = devices[i].deviceInfo.label;
nicSpec.device.deviceInfo.summary = devices[i].deviceInfo.summary;
nicSpec.device.backing = new VcVirtualEthernetCardDistributedVirtualPortBackingInfo();
nicSpec.device.backing.port = new VcDistributedVirtualSwitchPortConnection();
nicSpec.device.backing.port.switchUuid = portGroup.config.distributedVirtualSwitch.uuid;
nicSpec.device.backing.port.portgroupKey = portGroup.key;
nicSpec.device.connectable = new VcVirtualDeviceConnectInfo();
nicSpec.device.connectable.startConnected = devices[i].connectable.startConnected;
nicSpec.device.connectable.allowGuestControl = devices[i].connectable.allowGuestControl;
nicSpec.device.connectable.connected = devices[i].connectable.connected;
nicSpec.device.connectable.status = devices[i].connectable.status;
nicSpec.device.controllerKey = devices[i].controllerKey;
nicSpec.device.unitNumber = devices[i].unitNumber;
nicSpec.device.addressType = devices[i].addressType;
nicSpec.device.macAddress = devices[i].macAddress;
nicSpec.device.wakeOnLanEnabled = devices[i].wakeOnLanEnabled;
//Push change spec to device change variable
myDeviceChange.push(nicSpec);
}
}
spec.deviceChange = myDeviceChange
System.log("DeviceChange Spec is: " + spec.deviceChange);
return vm.reconfigVM_Task(spec);
