I googled this and came across 2 purported
solutions, neither of which worked.
1. Uninstall package biosdevname and reboot.
That did not prevent udevd from renaming eth0 to em1.
2. 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.
$ dmesg | grep em1
[ 5.949297] udevd[219]: renamed network interface eth0 to em1
$ ifconfig eth0
eth0: error fetching interface information: Device not found
$ cat /etc/udev/rules.d/70-persistent-net.rules
# This file was automatically generated by the /lib/udev/write_net_rules

# You can modify it, as long as you keep each rule on a single

# PCI device 0x168c:0x0023 (ath9k)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*",
ATTR{address}=="edited-out", ATTR{dev_id}=="0x0", ATTR{type}=="1",
KERNEL=="wlan*", NAME="wlan0"
# PCI device 0x1039:0x0900 (sis900)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*",
ATTR{address}=="edited-out", ATTR{dev_id}=="0x0",
ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"
# USB device 0x0bda:0x8187 (usb) (custom name provided by external tool)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*",
ATTR{address}=="edited-out", ATTR{dev_id}=="0x0", ATTR{type}=="1",
KERNEL=="wlan*", NAME="wlan1"
So, does anyone have any other suggestion how to
prevent udevd from renaming eth0 to em1?
