I have installed CentOS 7. I added "biosdevname=0 net.ifnames=0" at install time.
What I've done on Fedora for awhile now.
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.
