Hyper-V How To: Clear All Virtual Networking using Script


Some friends here on the Hyper-V team shared a PowerShell 2.0 script for clearing all the VM’s networking objects:



# Clear out all Virtual Networking objects


# WARNING: Do not run this script remotely, as it will interrupt any network
# connections during execution and restore normal, non-virtual networking on completion


$vsms = gwmi -namespace root\virtualization Msvm_VirtualSwitchManagementService
gwmi -namespace root\virtualization Msvm_InternalEthernetPort |`
    foreach{$vsms.DeleteInternalEthernetPort($_)}


gwmi -namespace root\virtualization Msvm_VirtualSwitch |`
    foreach{$vsms.DeleteSwitch($_)}


gwmi -namespace root\virtualization Msvm_ExternalEthernetPort |`
    foreach{$vsms.UnbindExternalEthernetPort($_)}
