Problem with PowerCLI and Threads / Jobs

Hi,

I have a script Deploy-VM.ps1 which takes couple of parameters and deploys a VM into a large environment accordingly. The complete deployment procedure for a single VM takes around 10 minutes as I e.g. have to wait for sysprep to complete and the VM to be available on the network to do some post-deployment stuff. The goal is to deploy many thousand VM and doing so sequentially will take around half a year

So what I need is the Deploy-VM script to called multiple time so the tasks can run in parallel - say 10 at a time.

$job = {

        .\Deploy-VD.ps1 `

                -name $args[0] `

                -clusterName $args[1] `

                -folder $args[2] `

                -template $args[3] `

                -custSpecName $args[4] `

                -numCPU $args[5] `

                -memoryGB $args[6] `

                -diskGB $args[7] `

}

Write-Host "Beginning deployment of 5 VDs in parallel..."

Start-Job -ScriptBlock $job -ArgumentList 'vm001', ...

Start-Job -ScriptBlock $job -ArgumentList 'vm002', ...

Start-Job -ScriptBlock $job -ArgumentList 'vm003', ...

Start-Job -ScriptBlock $job -ArgumentList 'vm004', ...

Start-Job -ScriptBlock $job -ArgumentList 'vm005', ...

# wait for all jobs to complete

Get-Job | Wait-Job

Write-Host "Done!"

The problem I have with this this seems to be the vCenter connection. I can create it outside the job block but then it will not be there inside the block. I could add the Connect-VIServer inside the Deploy-VM.ps1 file but then a connection is created for EVERY deployment process and would require me to save the credentials in a variable and push them into the script via parameter.

Everything not every satisfying. Any ideas?

cheers
