[CentOS] KISS networking with CentOS 7

Hi,

I'm currently experimenting with CentOS 7 on a couple of installations. 
I'm reasonably proficient with CentOS 5.x and 6.x.

I'd like to manage networking using a more traditional approach (Keep It 
Simple Stupid). Here's what I tried so far, starting from a minimal install:

Install net-tools (to be able to use ifconfig).

Get rid of NetworkManager:

	# yum remove NetworkManager*

Add 'net.ifnames=0' and 'biosdevname=0' to kernel boot options to name 
interfaces eth0, eth1, etc.

Edit '/etc/sysconfig/network-scripts/ifcfg-eth{0,1}' like I did under 
previous versions.

Eventually, edit '/etc/udev/rules.d/70-persistent-net.rules' to switch 
interfaces:

# /etc/udev/rules.d/70-persistent-net.rules
#
# eth0
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", \
   ATTR{address}=="00:1e:c9:42:84:7b", ATTR{type}=="1", \
   KERNEL=="eth*", NAME="eth0"
# eth1
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", \
   ATTR{address}=="00:30:f1:6a:2f:40", ATTR{type}=="1", \
   KERNEL=="eth*", NAME="eth1"

So far, no way to bring either eth0 or eth1 up. What am I doing wrong 
here? Is NetworkManager now a mandatory part of the base system? Some 
other mistake somewhere else? I'm a bit puzzled here.

Cheers,

Niki
