What does your configuration look like?
Can you post the content of /etc/sysconfig/network-scripts/ifcfg-eth0 and /etc/sysconfig/network?

I know this thread is super old, but it came first in a google search, so i thought I would post how I solved it.

In /etc/sysconfig/network-scripts/ifcfg-eth1 I had accidentially set DEVICE=eth0. Since the eth0 device already exists, that is why I received the error. Hope this will help someone else looking for a solution.

ABSTRACT:

file: where $interface is your interface, i.e.: eth0, p3p1, etc.

Contains old MAC address of the interface, but the script file exists, therefore conflict in configuration.
ie.: Service tries to use detected setings, but ifcfg script exists, therefore "File exists" error.


SOLUTION:

Fix the MAC address in the script file, with MAC address from:
--> If I find better solution, than fixing by hand, I may update this post.

An ancient post, but with a possibly newer answer for a Debian 8 system -

Make sure that /etc/network/interfaces have no extraneous lines, especially if configurijng for a static network.

Check with ifconfig, and if what you want is already there, dont repeat it.

Also: updates may mess with the network card location. often changing it to eth1. Resetting to eth0 may help . Easily checked wit the
service networking restart
command

Matt I am an experienced sys admin but you just saved me time - i copied the ifcfg files and forgot to change eth0 to eth1. Thanks!
