I am trying to override the mac addr.  Now this is on an armv7 actually
running the F19 kernel and Redsleeve 6, but it SHOULD be standard
Centos6 ifcfg-eth0 content.  Of course RSEL does not start with a
ifcfg-eth0 file, letting network services do all the work, so I am
starting from scratch, using the file from one of my C6 boxes with
static addressing.  My file has in it:
DEVICE="eth0"
BOOTPROTO=none
NM_CONTROLLED="no"
ONBOOT="yes"
TYPE="Ethernet"
NAME="System eth0"
DNS1=208.83.67.188
GATEWAY="208.83.67.177"
IPADDR="208.83.67.179"
HOSTNAME="rigel2.htt-consult.com"
IPV6INIT="yes"
MACADDR=02:67:15:00:01:79
MTU=1500
that's easy - you need to tell it the physical too
works from Fedora 10 up to Fedora 20 that way
[root@srv-rhsoft:~]$ cat ifcfg-eth1
DEVICE=eth1
HWADDR=68:05:ca:0d:62:c1
MACADDR=00:50:8d:b5:cc:de
"00:50:8d:b5:cc:de" is the on my interface has after it is up
"68:05:ca:0d:62:c1" is the pysical one of the device before fake it
[root@srv-rhsoft:~]$ ifconfig eth1
eth1: flags=67<UP,BROADCAST,RUNNING>  mtu 1500
         inet 62.178.103.85  netmask 255.255.255.0  broadcast 255.255.255.255

Shutting down loopback interface:  [  OK  ]

Bringing up interface eth0:  Device eth0 has different MAC address than 
expected, ignoring.
[FAILED]
And now not even an eth1 interface.
