Disk Image creation
Making a disk image of your computer means that it is an exact copy. So first you need to surf through your system and remove things you don't want present on the new machine. One important thing to remove (on a Linux system) is the file 70-persistent-net.rules. This file will copy the important device specific information like the IP address to the new machine. Open a terminal prompt and cd into /etc/udev/rules.d and then do an ls. You should see the file 70-persistent-net.rules.
