Post P2V Tasks

P2V does not end with migrating a Physical Server to Virtual Server  but there are certain post P2V tasks that could help in improving the performance of the converted server. 

  • Ensure you install VMware Tools on the migrated VM without fail.
  • Remove all unwanted hardware components from a migrated virtual server like serial ports and floppy drives.
  • Change the CPU and memory of the VM as per requirement and do not go with default values as they reflect the resources as in the Physical Server.
  • Physical Servers are installed with OEM drivers which are resource consuming and these drivers can be removed using Add/Remove Programs once they have been converted to VMs.

I came across a HP utility that can be download from here  which can be used to remove HP PSP with a single click.

One of the issue that is reported is the error when they get when try to assign IP to the migrated server –  ” The IP address XXX.XXX.XXX.XXX…” is already assigned to another adapter”.

This error message is caused by Ghosted NIC Cards that are present. These are the NIC cards that are converted as part of the P2V process since they were part of the physical Server but does not show up on the device manager. Follow the below mentioned steps to uninstall the ghost NIC cards.

  • Click Start –>Run–>Cmd [ Open a Command prompt]
  • Type in “set devmgr_show_nonpresent_devices=1” [ This change would display all non-present devices in device manager]
  • From the command prompt, type in “devmgmt.msc” [Do not go to Run prompt to open device manager or open from a GUI since above change would be effective from cmd prompt only]


  • Click View –>Show Hidden Devices
  • Non-Present devices are grayed out and can be uninstalled from the server. In this case  out NIC cards has to be uninstalled.


  • Now try assigning the IP back to the NIC card in the Virtual Server and should work fine.

IP Address issue has been addressed by Microsot here and VMware here and lot of other bloggers too.
