No VM Vim Reference

[abassoonkid]

An odd problem is cropping up when I try to migrate my application (that uses the vCloud Java SDK) from one network to another. As far as I can tell, I've set up everything the same on each network, from the vCloud Director settings to the templates used, and yet the code returns NULL when I try to run the getVMVimRef() function (off a VM, of course). Any ideas as to what could cause a VM to not have a Vim reference?

[abassoonkid]

Anyone have any useful information on this or at least seen something like this occur?

Hi,

Are you trying to VappTemplate VM's - getVMVimRef();

And it throws "Vim Object Reference Not Found"

Sorry to get back to you so late. I'm getting a Null Pointer Exception.

This is the top line of the stacktrace:
com.vmware.vcloud.sdk.VM.getVMVimRef(VM.java:1090)

Hi,

Are you doing this operation as a System Admin/Organization Admin/User??

This information is only available to Sytem Admins. Even using as an Organization Admin/User should not throw a null pointer. It should be data not found or something.

I'm using a System Admin account

Hi,

Is this SDK 1.5 against vCD 1.5.

Can you post the SDK logs.

Hi,

Looks like a bug. I was referring to he Vapp VM's instead of the VappTemplate VM's.

As a workaround you can get that info like this.

Cose Snippet:

--------------------

VappTemplate vappTemp = VappTemplate.getVappTemplateById(vcloudClient,
"urn:vcloud:vapptemplate:9673a092-8ed0-4331-a764-812448285397");
List<VappTemplate> vappVms = vappTemp.getChildren();
for (VappTemplate vappVm : vappVms) {
for (VCloudExtensionType vcloudExtension : vappVm.getResource()
.getVCloudExtension()) {
for (Object jaxbObject : vcloudExtension.getAny()) {
if (((JAXBElement) jaxbObject).getValue() instanceof VmVimInfoType) {
VmVimInfoType vmVimInfoType = (((JAXBElement<VmVimInfoType>) jaxbObject))
.getValue();
System.out.println(vmVimInfoType.getVmVimObjectRef()
.getMoRef());
}
}
}
}

I am using both the SDK 1.5 and vCD 1.5.

I've looked through the logs (request, debug, etc.) and I don't see any errors. Is there a different path that the SDK log is at?

[abassoonkid]

I'm refering to a Vapp's VMs as well. Can I use the same sort of code for a Vapp's VMs as opposed to a VAppTemplate's?

[rkamal]

Hi,

For Vapp's VM,

    You should be able use the VM -> getVMVimRef() - This should work fine.

For VappTemplate's VM,

    VappTemplate -> getVMVimRef() - This looks like a bug. For this you can use the above code snippet only for this.

I'm getting this bug for while using that call on the Vapp's VMs...

[rkamal]

Hi,

I was able to get the Vapp vm's vim object reference.

Vapp vapp = Vapp.getVappById(vcloudClient, "urn:vcloud:vapp:2f93cc90-d787-4dcf-9e1a-ec47a780056b");
VM vm = vapp.getChildrenVms().get(0);
System.out.println(vm.getVMVimRef().getMoRef());

I understand that, and I stated in my first post that I can get it to work on my first network, but when deploying it on a different network, this problem crops up.

[rkamal]

Hi,

Can you post the Vapp xml logs which gets logged on the console.

Setting this would spit all the XML logs from the SDK.

VcloudClient.setLogLevel(Level.All);

Regards,

Rajesh Kamal.

[abassoonkid]

I'll work on that.

I tried your other code for the VApp's Vms, and I'm getting an empty list on the first call (vm.getResource().getVCloudExtension())

[abassoonkid]

I figured out the problem. It seems like vCD couldn't communicate with vCenter correctly and thus wasn't giving back the reference to vCenter. I turned of a firewall in vCenter and everything worked.

Hi Rajesh,

I am facing similar issue in orchestrator workflow, when I am  trying to convert VCD vApps vm to vCenter vm .  When I try to run the getVMVimRef() function (off a VM) it throw error “Vim Object Reference Not Found”.

Any ideas as to what could cause a VM to not have a Vim reference?

My workflow code is as listed below

var vcVms = new Array();

System.log("Vms passed in: " + vms.length);

for (var i in vms) {

    var moref = vms[i].getVMVimRef().moRef;

    var XPath = "xpath:id='"+ moref +"'";

    var VMs  = VcPlugin.getAllVirtualMachines(null, XPath);

    var vm = VMs[0];

    var vmName = vm.name;

    vcVms[i] = vm;

}

--AVR

The vCloud VM always has a moRef. Are you sure that the array contains vCloud VM Objects ? ? Have you tried your script with a single vCloud:VM object ?

I am using exactly the same script to get a vCenter VM from vCloud VM.

var vmmoref = vCloudVM.getVMVimRef().moRef;
var xpath = "xpath:id='"+ vmmoref +"'";

var vms = VcPlugin.getAllVirtualMachines(null , xpath);

vm=vms[0];

[anuragvr]

Yes, array contains the VM objects as when I print following

System.log("Vms passed in: " + vms.length);

System.log("vCloud VM: " + vms[i].name);

System.log(vms[i]);

var moref = vms[i].getVMVimRef().moRef;

It prints arrays actual length 2 and VM name. this scriptable task taking vm array as input from action “getVms FromVApp”

Log subtracts for reference
