Each NIC is unique and UDEV assigns a unique name to each one. Since

not assign it to another NIC even if the original NIC has been
removed. This way UDEV will never assign the same name to more that

You can change this manually by modifying the UDEV config files.

in a way that the original hardware is offline and that new hardware
has been added to the same machine. Hence the new NIC is given a
Although it can be done it is not a good idea to just move the OS HD

Doing this will cause issues like this one and may give other
