A. I recently had a situation where a VM was auto-provisioned using a boot from network. To boot over the network, a Hyper-V VM must use an emulated NIC, but once the VM was provisioned, I needed to remove the emulated NIC in favor of the much better performing synthetic NIC.

The script below removes all emulated NICs from a passed VM. Save this as removevmlegacyNIC.ps1 and replace the name of the VMMServer with your SCVMM Server.

 

# Connect to the VMM server.                              $VMMServer = Get-VMMServer -ComputerName "savdalvmm01.savilltech.net"                              # Ensure that the virtual machine is stopped.                              If ($args\\[0\\].StatusString -ne "Stopped")                              \\{                              Stop-VM -VM $args\\[0\\]                              \\}                              get-vm $args\\[0\\] |select -ExpandProperty VirtualNetworkAdapters | where \\{$_.VirtualNetworkAdapterType -eq "Emulated"\\} | Remove-VirtualNetworkAdapter                              

 

To use it, just run the following from a SCVMM PowerShell prompt:

 

.\removevmlegacyNIC.ps1 savdalclient2
