Network config after P2V

After a physical to virtual (P2V) conversion of a machine, you cannot assign an IP address to a NIC, the ip address which used in physical is existing.

What we do is uninstall the physical adapter and driver in the vm.

1. 1. Right-click the My Computer desktop icon and choose Properties.
   2. Click the Advanced tab and select Environment Variables.
   3. In the System variables section, click New.
   4. Set the Variable name to devmgr_show_nonpresent_devices and set the Variable value to 1 to enable the parameter.
   5. Click OK to add the variable to Windows.
      
2. Start the Device Manager by running this command from the same command prompt:
   
   start devmgmt.msc
   
3. Click View > Show Hidden Devices.
4. Expand the Network Adapters tree (click the plus sign next to the Network adapters entry).
5. Right-click the dimmed network adapter, then click Uninstall.
6. Once all of the grayed out NICs are uninstalled, assign the IP address to the virtual NIC.
