script needed to check for a config parameter for a VM

[PruDev]

Hi Guys,

I'm looking for a script that will check a config parameter of a group of VMs and return its value. The specific parameter I'm looking for is

devices.hotplug = false

..this basically prevents the virtual NIC from showing up as a removable device and prevents users from accidentally killing their session.

If anyone has this script handy, that would be terrific.

Thanks!

The next function will check the devices.hotplug config parameter of a VM:

function Get-DevicesHotplug {
  param([Parameter(Mandatory=$true,ValueFromPipeline=$true)]
        [http://VMware.VimAutomation.ViCore.Impl.V1.Inventory.VirtualMachineImpl|http://VMware.VimAutomation.ViCore.Impl.V1.Inventory.VirtualMachineImpl] $vm)

  process {
    $Report = "" | Select-Object -Property Name,"devices.hotplug"
    $Report.Name = $vm.Name
    $DevicesHotplug = $vm.ExtensionData.Config.ExtraConfig | Where-Object { $_.Key -eq "devices.hotplug" }
    if ($DevicesHotplug) {
      $Report."devices.hotplug" = $DevicesHotplug.Value
    }
    else {
      $Report."devices.hotplug" = ""
    }
    $Report
  }
}

To check all your virtual machines with this function you can do:

Get-VM | Get-DevicesHotplug

The following function will set the devices.hotplug to false:

function Disable-DevicesHotplug {
  param([Parameter(Mandatory=$true,ValueFromPipeline=$true)]
        [http://VMware.VimAutomation.ViCore.Impl.V1.Inventory.VirtualMachineImpl|http://VMware.VimAutomation.ViCore.Impl.V1.Inventory.VirtualMachineImpl] $vm)

  process {
    $vmview = $vm | Get-View
    $vmConfigSpec = New-Object VMware.Vim.VirtualMachineConfigSpec

    $extra = New-Object VMware.Vim.optionvalue
    $extra.Key="devices.hotplug"
    $extra.Value="false"
    $vmConfigSpec.extraconfig += $extra

    $vmview.ReconfigVM($vmConfigSpec)
  }
}

To set the devices.hotplug to false for all your virtual machines you can do:

Get-VM | Disable-DevicesHotplug

The functions use PowerCLI v4.1 type declarations. So be sure to use PowerCLI v4.1.

Because the forum software has troubles with square brackets and the functions use them I attached the functions to the post. Use only the attached functions and not the functions that are included in the text!
