Enable VM Hot-Add CPU/Memory on reboot

Hi All,

Does anyone know of a way to automatically enable Hot-Add when a machine is rebooted?  I have been trying to use this script that I found at https://communities.vmware.com/thread/287941:

Function Enable-vCpuAndMemHotAdd($vm){ 

  $vmConfigSpec = New-Object VMware.Vim.VirtualMachineConfigSpec 

  $extra1 = New-Object VMware.Vim.optionvalue 

  $extra1.Key="mem.hotadd" 

  $extra1.Value="true" 

  $vmConfigSpec.extraconfig += $extra1 

  $extra2 = New-Object VMware.Vim.optionvalue 

  $extra2.Key="vcpu.hotadd" 

  $extra2.Value="true" 

  $vmConfigSpec.extraconfig += $extra2 

  $vm.Extensiondata.ReconfigVM($vmConfigSpec) 

} 

Get-Content  "c:\listofvms.txt" | %{ 

   $vm = Get-VM -Name $_ 

   Enable-vCpuAndMemHotAdd $vm  

}

It works great when the VMs are powered off, but does not make the change if they are running.  Does anyone know of a way to modify this script so that the new setting will take effect the next time the VM is rebooted?

Thanks
