Look in /etc/udev/rules.d/ for a file


It is probably there assigning the MAC address you want on eth0 to eth1.
Likely it has two assignment lines. Just changing the assignment on the
address, a single character edit, and deleting the other line should be all
you need to do before rebooting to find what you expected in the first

Adding a zero byte file


in rules.d/ might help to avoid future perplexity. See (near its bottom):

There are just two lines in 70-persistent-net.rules. Both have an ATTR(address) entry, but the ATTR(dev_id)=="0x0 and the ATTR(type)=="1". I have forgotten how to determine the MAC address. lspci shows a lot of info, but no mac address.

Have you tried the command "hwinfo --network" as root?

On my running machine it shows all the available info on my NICs,
including the "HW Address:" which is the MAC address.
