Re: Trouble adding more "CIVM" to a "CIVApp" in vC...

AlfredCrackhamm · ‎11-07-2013

Hi All,

I am having trouble performing some tasks in PowerCLI that I can do easily in the GUI.

Firstly, in the vCloud Director GUI, I can create a new vApp from a template that has one machine in it. I can also do that task from PowerCLI with something like the following code:

Connect-CIServer -server x.x.x.x -user ***** -org org-development -Password *****
$myVappName = 'TestApp03'
$myTemplate = Get-CIVAppTemplate -Name 'vWin2012-Template'
$myOrgVdc = Get-OrgVdc -Name 'vOrgDevelopment'
New-CIVApp -Name $myVappName -Description "Testonly." -OrgVdc $myOrgVdc -VAppTemplate $myTemplate

If I want to add some more VM's to this newly create vApp 'TestApp03', I can do it easily in the vCloud Director web GUI by browsing to the Virtual machines for the vApp, then on the actions click "add VM". I can then add several more copies of the VM from the template.

My problem is how do I perform this same action in PowerCLI ? How to add more machines from an existing template into an existing vApp ?

I want to only use "CI" type cmdlets and avoid having to "Connect-VIServer".
The version of PowerCLI that I have installed is "VMware-PowerCLI-5.5.0-1295336.exe"

Any insights or assistance is greatly appreciated.

Hi,

We are looking to do the same thing. I tried to use the re-compose option but got an error with the following code:

$vmstoaddnames = "Machine1,Machine2"
$vmstoaddnames = $vmstoaddnames -split(",")
$civapp = get-civapp "Dean Test"
$cat = Get-CIVAppTemplate "Build 29.08"


$vmstoadd =  $cat.ExtensionData.Children.Vm |? { $vmstoaddnames -contains $_.name }


$refstovmstoadd = $vmstoadd | % {
     $ref = new-object vmware.vimautomation.cloud.views.reference
     $ref.href = $_.href
     $ref
}


$recomposeparams = new-object vmware.vimautomation.cloud.views.recomposevappparams
$recomposeparams.CreateItem = $refstovmstoadd
$recompose = $civapp.extensiondata.recomposevapp_task($recomposeparams)
}

Exception setting "CreateItem": "Cannot convert the "VMware.VimAutomation.Cloud.Views.Reference" value of type

"VMware.VimAutomation.Cloud.Views.Reference" to type "VMware.VimAutomation.Cloud.Views.Vm"."

At line:8 char:1

+ $recomposeparams.CreateItem = $refstovmstoadd

Any help would be appreciated....

Here is a script that I used to add a VM to a vApp. You would like to trim the parts that you probably don't need (networking, computer name) and probably refine it. Reading it backwards might be easier.

Some remarks on your script and the error:

You are trying to assign references to CreateItem. CreateItem is used when you want to create a VM from scratch in the vApp. To use a template VM, set the SourcedItem property instead of CreateItem and set its source to the references that you try to currently assign to CreateItem.

Thanks Atanas, with some slight modifications I was able to get your script working as expected! I guess I was way off the mark Great work!

I am getting the below error on running the RecomposeVApp command :

Could you suggest which access is missing here ? !
