Removing a Network Adapter To A VM Using The Hyper-V WMI V2 Namespace

Relating to my previous posts regarding Adding a Network Adapter To A VM Using The Hyper-V WMI V2 Namespace and Connecting a VM Network Adapter To A Switch Using The Hyper-V WMI V2 Namespace I had some questions come in around removing a NIC.  So here’s a sample – it’s pretty simple…

Removing a NIC

 $vmName = "Test" 

 #Retrieve the Hyper-V Management Service, ComputerSystem class for the VM and the VM’s SettingData class. 
$Msvm_VirtualSystemManagementService = Get-WmiObject -Namespace root\virtualization\v2 `
      -Class Msvm_VirtualSystemManagementService 

$Msvm_ComputerSystem = Get-WmiObject -Namespace root\virtualization\v2 `
      -Class Msvm_ComputerSystem -Filter "ElementName='$vmName'" 

$Msvm_VirtualSystemSettingData = ($Msvm_ComputerSystem.GetRelated("Msvm_VirtualSystemSettingData", `
     "Msvm_SettingsDefineState", `
      $null, `
      $null, ` 
     "SettingData", `
     "ManagedElement", `
      $false, $null) | % {$_}) 


#Retrieve the NetworkAdapterPortSettings Associated to the VM. 
$Msvm_SyntheticEthernetPortSettingData = ($Msvm_VirtualSystemSettingData.GetRelated(` 
     "Msvm_SyntheticEthernetPortSettingData") `
      | Where-Object {$_.ElementName -eq "Network Adapter"}) 

#Call the RemoveResourceSettings function with the path to network adapater
$Msvm_VirtualSystemManagementService.RemoveResourceSettings($Msvm_SyntheticEthernetPortSettingData)
