After converting a physical to a virtual, there is some clean-up that should be done.
Non-existing hardware devices should be removed.
Software which controlled the legacy hardware should be uninstalled.
Here’s how to uninstall the old hardware:
1) Open a command-prompt and type:
“set devmgr_show_nonpresent_devices=1” (without quotes), hit Enter
now type:
“start devmgmt.msc”
Leave the command window open!
2) Click on “View –> Show hidden devices”
3) Expand all the device trees and right-click/uninstall the ghosted devices
All done! Nice and clean. Don’t forget to un-install any old software packages such as vendor hardware management and RAID controller software that might not be needed
