datapath-windows: Add WMI Script that updates Hyper-V friendly port names.
The following script leverage's the advantages of WMI infrastructure
offered in Hyper-V.
This scripts allows the user to change the
Msvm_EthernetPortAllocationSettingData property of a VM network adapter
connected to a Hyper-V Virtual Switch.
Usage:
import-module .\OVS.psm1
$vnic = Get-VMNetworkAdapter VM1
Connect-VMNetworkAdapter -VMNetworkAdapter $vnic -SwitchName external
$vnic | Set-VMNetworkAdapterOVSPort -OVSPortName ovs-port-1
VM1 - is a VM on top of a Hyper-V
external - is a Hyper-V Virtual Switch
