Reconfig_VM Task For Network Adapter Change

[Ashwin89]

Hello.

I am having two network adapters A and B.

Currently I am on Network Adapter A and I want to switch on B through ReConfig_VM Task() API.

Can somone help me in specifying VirtualmachineConfigSpec?

This is how I am specifying the virtualmachineconfigspec but i am not able to acheive it.

VirtualMachineConfigSpec Configspec = new VirtualMachineConfigSpec();

VirtualDeviceConfigSpec[] nicSpec = new VirtualDeviceConfigSpec[1];

VirtualEthernetCard nic = new VirtualVmxnet();

VirtualEthernetCardNetworkBackingInfo nicBacking = new VirtualEthernetCardNetworkBackingInfo();

nicBacking.deviceName = "B";

Configspec.deviceChange = nicSpec;

nic.backing = nicBacking;

nicSpec[0].device = nic;

ConfigSpec.devicechange = niSpec;

Thanks,

Following code snippet might be of help illustrating adding a nic.

// Add a NIC

VirtualDeviceConfigSpec nicSpec = new VirtualDeviceConfigSpec();

if(networkRef != null)

{

nicSpec.operation = VirtualDeviceConfigSpecOperation.add;

nicSpec.operationSpecified = true;

VirtualEthernetCard nic = new VirtualVmxnet();

VirtualEthernetCardNetworkBackingInfo nicBacking = new VirtualEthernetCardNetworkBackingInfo();

nicBacking.network = networkRef;

nicBacking.deviceName = networkName;

nic.addressType = "generated";

nic.backing = nicBacking;

nic.key = 4;

nicSpec.device = nic;

}

I guess method that you have suggested will add new network adapeter.

Whether this will also work for replacing the network adpapter from the list of exisiting adapters?

Here is code snippet for which i am getting invalid configuration for device 0 when i call reconifgvm_task api.

// Here I get the list of Network adapters

ManagedObjectReference[] nwMoref = (ManagedObjectReference[])_GetPropFromMoref(PaMoref, "network");

//Suppose I want to edit the network adapter for a VM to default i.e VM Network which is 2nd in the list.

VirtualDeviceConfigSpec nicSpec = new VirtualDeviceConfigSpec();

nicSpec.operation = VirtualDeviceConfigSpecOperation.edit; //As we want to edit the network adapter

nicSpec.operationSpecified = true;

VirtualEthernetCard nic = new VirtualVmxnet();

VirtualEthernetCardNetworkBackingInfo nicBacking = new VirtualEthernetCardNetworkBackingInfo();

nicBacking.network = nwMoref[1]; //Second in the network list.

nicBacking.deviceName = "VM Network"; //I am not sure what should we give the device name?

nic.backing = nicBacking;

nicSpec.device = nic;

it throwing me message as Invalid configuration for device 0.

Whether I am doing any wrong settings?

Please let me know for the same.

The code snippet seems to be correct. You have specified the deviceName as "VM Network". Is this the name for the network that you are assigning in the following:

nicBacking.network = nwMoref[1];

Try to change the name and see if it works.

I am trying to add a new ethernet card to a VM - there are no errors from the code. However the vSphere client connected to the host shows this:

Invalid  configuration for  device '0'

My network configuration looks like this:

What I am trying to do is add a new ethernet card to node01 which will connect it to "MyNewPortGroup" on "MyNewSwitch" which I created programmatically earlier on.

The code I used for the reconfiguration is below (C#):

public void ChangeVEthernetCard()
        {
            ManagedObjectReference portGrp = new ManagedObjectReference { Value = "HaNetwork-MyNewPortGroup", type = "Network" };
            VirtualEthernetCard newEthernetCard = new VirtualEthernetCard();
            
            VirtualEthernetCardNetworkBackingInfo backingInfo = new VirtualEthernetCardNetworkBackingInfo();
            backingInfo.network = portGrp;
            backingInfo.deviceName = "MyNewPortGroup";
            newEthernetCard.addressType = "generated";
            newEthernetCard.backing = backingInfo;
            VirtualDeviceConfigSpec deviceSpec = new VirtualDeviceConfigSpec();
            deviceSpec.device = newEthernetCard;
            deviceSpec.operation = VirtualDeviceConfigSpecOperation.add;
            deviceSpec.operationSpecified = true;
            VirtualMachineConfigSpec newMachineSpec = new VirtualMachineConfigSpec();
            newMachineSpec.deviceChange = new VirtualDeviceConfigSpec[] { deviceSpec };
            
            try
            {
                ManagedObjectReference updateTask = _host.VimService.ReconfigVM_Task(_MOR, newMachineSpec);
                Debug.WriteLine("Updated vm");
            }
            catch (System.Web.Services.Protocols.SoapException e)
            {
                ExceptionHandler.SoapExceptionHandler(e);
            }
            catch (Exception e)
            {
                ExceptionHandler.GenericExceptionHandler(e);
            }
        }

I picked up the value of the port group MOR from my MOB. Do I have the correct value for backingInfo.deviceName?

I used this thread and this one: http://communities.vmware.com/message/1146914#1146914 as a reference while writing my code.

Any help would be appreciated.

I got it to work by using VirutalPCNet32 instead of VirutalEthernetCard.
