Remove network adapter

[orian]

Hi,

I want to go over a list of virtual machines and remove their network adapter.

Is there a workflow that receives an array of virtual machines and removes the  network adapter?

If no, someone create a workflow\script which do it?

Thanks!

You could use the combination of Get-VM and Remove-networkAdapter cmdlets. First of you can create a list VMs in a csv file and use the below. Assuming the column header for the VMs is VMName.

$VMs = Import-Csv C:\VMs.csv

foreach ($VM in $VMs) {

Get-VM -Name $VM.VMName | Remove-NetworkAdapter

}

Get-VM - vSphere PowerCLI Cmdlets Reference

Remove-NetworkAdapter - vSphere PowerCLI Cmdlets Reference

Hope this helps.

Hi,

Thanks, but these are powershell commands, that can be use only with invoke script.

Is there a java script that can be used through the vmware orchestrator?

No, I wouldn't be aware of that as I have no experience with Orchestrator. Somebody on the community should be able to help.

Here is some sample code to remove network adapters from a single virtual machine (vm input parameter)

var nicsToRemove = [];

for each (var device in vm.config.hardware.device) {  
  if (device instanceof VcVirtualVmxnet  
   || device instanceof VcVirtualVmxnet2  
   || device instanceof VcVirtualVmxnet3
   || device instanceof VcVirtualE1000  
   || device instanceof VcVirtualPCNet32  
   || device instanceof VcVirtualEthernetCard) {
    // Here you can add some custom logic to decide whether to remove the network adapter
    // This sample code will remove all network adapters
      nicsToRemove.push(device);  
  }
}  

var vmConfigSpec = new VcVirtualMachineConfigSpec();  
var deviceChanges = [];
var deviceConfigSpec = new VcVirtualDeviceConfigSpec() ;  

for each (var nic in nicsToRemove) {  
  deviceConfigSpec.operation = VcVirtualDeviceConfigSpecOperation.remove;  
  deviceConfigSpec.device = nic;  

  deviceChanges.push(deviceConfigSpec);  
}  

vmConfigSpec.deviceChange = deviceChanges;  

try {  
  myTask = vm.reconfigVM_Task(vmConfigSpec);  
} catch (ex) {  
  System.warn("Error while reconfiguring VM: " + ex);  
}

Wow, Thank you for the code!

Do you have a similar code for adding a network adapter?

[iiliev]

Here it is (you may want to experiment with deviceConfigSpec parameters eg. if you want to add different type of network adapter)

var vmConfigSpec = new VcVirtualMachineConfigSpec();  
var deviceConfigSpec = new VcVirtualDeviceConfigSpec();  

deviceConfigSpec.operation = VcVirtualDeviceConfigSpecOperation.add;
deviceConfigSpec.device = new VcVirtualE1000();
deviceConfigSpec.device.key = -100;
deviceConfigSpec.device.backing = new VcVirtualEthernetCardNetworkBackingInfo();
deviceConfigSpec.device.backing.deviceName = "VM Network";
deviceConfigSpec.device.connectable = new VcVirtualDeviceConnectInfo();
deviceConfigSpec.device.connectable.startConnected = true;
deviceConfigSpec.device.connectable.allowGuestControl = true;
deviceConfigSpec.device.connectable.connected = true;
deviceConfigSpec.device.controllerKey = 100;
deviceConfigSpec.device.addressType = "generated";
deviceConfigSpec.device.wakeOnLanEnabled = true;

vmConfigSpec.deviceChange = [deviceConfigSpec];  

try {  
  myTask = vm.reconfigVM_Task(vmConfigSpec);  
} catch (ex) {  
  System.warn("Error while reconfiguring VM: " + ex);  
}

Thank you again!

I think I will love this product.

Another question:

I'm familiar with powershell commands, but I'm a beginner with VMware orechestrator and java script

How can I find easily these classes that you use in the last scripts? I know there is a search box, but when I search "network" I receive a lot of attribute\methods\scripts - can you give me some tips for an easy start?

another question:

Is there an easy way to configure IP address, subnet, default gateway for the new network adapter?

for now, I use Invoke-vmscript command, which take a while because of the connection progress to the vcenter.

Hi,

When I run the remove network code, I sometimes receive in the vSphere the following error:

Invalid configuration for device '1'.

What should I change in the code?

Thanks!

Hi, do you know after i add a NIC to a VM how can i identify the NIC and configure settings to it: IP, gateway, subnet mask, dns. I have a powershell script to do that in windows but still need to figure out how to tell the script which NIC to apply the config too. I could pass the MAC address but would need to find out which is the MAC of the new NIC, is there a better way using the vSphere API so that i can use it both in win and linux? thanks
