Remove network adapter from running vm?

[jwblake]

Im attempting to remove a network adapter from from a script and the machine needs to stay powered on. I try:

Get-NetworkAdapter $vmname | where { $_.NetworkName -eq "10 Network" } | Remove-NetworkAdapter

Remove-NetworkAdapter : 9/28/2011 3:59:24 PM    Remove-NetworkAdapter        The VM must be in the following state: PoweredOff.
At line:1 char:101
+ Get-NetworkAdapter W7-AutoPrv003 | where { $_.NetworkName -eq "10 Network" } | Remove-NetworkAdapter <<<<
    + CategoryInfo          : InvalidOperation: (PoweredOn:PowerState) [Remove-NetworkAdapter], ViError
    + FullyQualifiedErrorId : Common_SharedParameterHelper_VerifyVmIsInState_VmNotInState,VMware.VimAutomation.ViCore.Cmdlets.Commands.RemoveNetworkAdapter

i would really thing that there a way to remove the NIC while the VM is powered on?

There is with the ReconfigVM_Task method.

$vm = Get-VM MyVM 
$nic = $vm.ExtensionData.Config.Hardware.Device | where {$_.DeviceInfo.Label -eq "Network adapter 2"}

$spec = New-Object VMware.Vim.VirtualMachineConfigSpec 
$dev = New-Object VMware.Vim.VirtualDeviceConfigSpec 
$dev.operation = "remove" 
$dev.Device = $nic
$spec.DeviceChange += $dev

 $vm.ExtensionData.ReconfigVM($spec)

Don't know what the risk is though.

Off topic; I saw you at VMworld LucD, nice presentation.  Sorry to semi hi-jack the post.
