I have installed CentOS 7. I added "biosdevname=0 net.ifnames=0" at install time.
I still have a network name of en01 and not eth0.
How do I get eth0 when viewing ifconfig?
dmesg | grep eth0 show its being detected, and being renamed. systemd-udev renaming eth0 to en01...
I then looked in /etc/udev and dont see anything of value...
Thanks,
Jerry

I don't use NetworkManager, so if you are using it, I don't know, it does its own thing to network names.
Also, I do this when I have physical access to the machine.
First.
rpm -e biosdevname (This should soon not be necessary, at least in Fedora) Then in /etc/default edit grub and add the net.ifnames=0 at the end of the kernel line.
Then grub2-mkconfig -o /boot/grub2/grub.cfg which will put it into grub2.
Next I go into /etc/sysconfig/network-scripts and name the ifcfg-* file accordingly, and also edit said file from it's if or biosdev name to eth-whatever.
This has worked for me since Fedora began doing this.

Wouldn't there be some configuration changes necessary in the udev net rules? I can't speak for EL7, but in the past I've had to tweak things there (as well as network-scripts) when doing chassis and/or NIC swaps in servers.

I haven't had to touch it. Looking at a laptop I have with Fedora 20, /etc/udev/rules.d is empty, not sure about CentOS 7.
