I googled this and came across 2 purported solutions, neither of which worked.
- Uninstall package biosdevname and reboot.
That did not prevent udevd from renaming eth0 to em1.
- Add the line
biosdevname=0 to /boot/grub2/grub.cfg
That did not work either. Any other way to get around this renaming?
find out your MAC-address with "ifconfig -a" make a udev-rule like below (ONE line) for the MAC reboot the machine after that and you are done
[root@rh:~]$ cat /etc/udev/rules.d/70-persistent-net.rules # PCI device 0x8086:0x1502 (e1000e) SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="78:ac:c0:b1:76:e4", ATTR{dev_id}=="0x0", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"
I made the change and rebooted.

So, does anyone have any other suggestion how to prevent udevd from renaming eth0 to em1?
Here is what I wrote down for changing ethernet devices to any arbitrary name you want, including ethX, under Fedora 17 (15+, actually).

You don't need to mess with biosdevname, juts set/edit 70-persistent-net.rules (details described in the above link).
