How to remove hidden/inactive network cards

After a p2v operation some clean up tasks should be done.

One step is to remove non-existing hardware devices like “old” network cards (NICs):

  • open a command prompt on the virtualized server
  • type: set devmgr_show_nonpresent_devices=1
  • type: devmgmt.msc to open the device manager
  • the devicemanager opens – now select “view” – “show hidden devices”
  • expand the device tree and navigate to “network adapters”
  • select the displayed “ghost devices” and uninstall them
