Deploy VM using Remote PowerShell

[aladdchop]

We're trying to write a script to deploy VM's using Remote PowerShell.  If we execute locally it works every time.  If we execute remote it hangs in the same spot every time.  Anyone have any ideas?

$session = New-PSSession -ComputerName localhost -ConfigurationName Microsoft.PowerShell32

Invoke-Command -Session $session -ScriptBlock {

#Add the PowerCli Snapin

Add-PSSnapin VMware.VimAutomation.Core -ErrorAction SilentlyContinue

Add-PSSnapin VMware.VimAutomation.Vds -ErrorAction SilentlyContinue

Set-PowerCLIConfiguration -InvalidCertificateAction "Ignore" -Confirm:$false

#Set variables

[int]$SuccessCode = 1

  $hosts = @(

    "vcenter1",

    "vcenter2"

   );

$VCCred= "user"

$VCPwd= "psswrd"

$Domain= "mydomain.com"

$DNS1= "192.168.1.1"

$DNS2= "192.168.1.2"

$VMName = "LNX002"

$Template= "RHEL-SM-02"

$ClusterName= "Cluster"

$LUN = "SAN_LUN"

$VDPortGroup = "Public"

#Connect to VCenter Servers

Connect-VIServer -Server $hosts -User $VCCred -Password $VCPwd

#Deploy New VM

$Cluster = Get-Cluster -Name $ClusterName

$NewHost = Get-VMHost -Location $Cluster | Sort $_.MemoryUsageGB -Descending | Select -First 1

$NewDatastore = $NewHost | Get-Datastore | Where-Object -FilterScript {$_.Name -like "$LUN"} | Sort-Object -Descending -Property FreeSpace | Select-Object -Property Name, FreeSpaceMB -First 1

$custSpec = New-OSCustomizationSpec -Type NonPersistent -OSType Linux -NamingScheme Fixed -NamingPrefix LNX002 -DnsSuffix $Domain -Domain $Domain -DnsServer $DNS1,$DNS2

$CustSpec | Get-OSCustomizationNicMapping | Set-OSCustomizationNicMapping -IpMode UseDHCP

$NewVM = New-VM -Name $VMName -Template $Template -ResourcePool $ClusterName -Datastore $NewDatastore.Name -OSCustomizationSpec $custSpec

#$myNetworkAdapter = Get-VM -Name $VMName | Get-NetworkAdapter | Select-Object -First 1

$myVDPortGroup = Get-VDPortGroup -Name $VDPortGroup

#Set-NetworkAdapter -NetworkAdapter $myNetworkAdapter -Portgroup $myVDPortGroup -Confirm:$false

#Set-NetworkAdapter -NetworkAdapter $myNetworkAdapter -StartConnected:$true -Confirm:$false

Get-VM -Name $NewVM | Get-NetworkAdapter | Select-Object -First 1 | Set-NetworkAdapter -StartConnected:$true -Confirm:$false -RunAsync

****************************Script hangs right here**********************************************************************************

Get-VM -Name $NewVM | Get-NetworkAdapter | Select-Object -First 1 | Set-NetworkAdapter -Portgroup $myVDPortGroup -Confirm:$false -RunAsync

Get-VM -Name $NewVM | Start-VM -Confirm:$false

$DeployedVM = Get-VM -Name $NewVM

#$DeployedVM.PowerState

IF ($DeployedVM.PowerState -eq "PoweredOn") {

    $SuccessCode = 0

    }

ELSE {

    $SuccessCode = 1}

}

$SuccessCode = Invoke-Command -Session $session -ScriptBlock { $SuccessCode }

$SuccessCode

And where does it hang ? On the Add-PSSnapin ?

Any exceptions ?

[aladdchop]

Hangs right here.  No exception just won't go past this step.  (-RunAsync not required.  It was just something we tried to get past the hang.

Get-VM -Name $NewVM | Get-NetworkAdapter | Select-Object -First 1 | Set-NetworkAdapter -StartConnected:$true -Confirm:$false -RunAsync

****************************Script hangs right here**********************************************************************************

Get-VM -Name $NewVM | Get-NetworkAdapter | Select-Object -First 1 | Set-NetworkAdapter -Portgroup $myVDPortGroup -Confirm:$false -RunAsync

Get-VM -Name $NewVM | Start-VM -Confirm:$false

$DeployedVM = Get-VM -Name $NewVM

#$DeployedVM.PowerState

IF ($DeployedVM.PowerState -eq "PoweredOn") {

    $SuccessCode = 0

    }

ELSE {

    $SuccessCode = 1}

}

$SuccessCode = Invoke-Command -Session $session -ScriptBlock { $SuccessCode }

$SuccessCode

And do you get the same phenomena when you set up an interactive remote session and run that line ?

[aladdchop]

Nope, if we run it interactivity it work fine.

[LucD]

And you are sure you are running the script with the same account ?

Can you perhaps show how you start the remote session and start the script ?

[aladdchop]

Hi Luc,

Looks like you might be right.  Some weird authentication problem.  We took the code as it is and dropped it into our workflow and it worked fine.  Just plain weird.

Thanks for looking at it.
