I worked a bit on this. I no longer have the MAC or HW addrs in
ifcfg-eth0. Only in /etc/udev/rules.d/70-persistent-net.rules, and only
for name=eth0:
# net device ()
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*",
ATTR{address}=="02:67:15:00:01:79", ATTR{type}=="1", KERNEL=="eth*",
NAME="eth0"
but on reboot, I get the error:
Bringing up interface eth0: Device eth0 does not seem to be present,
delaying initialization.
[FAILED]
and the ethernet comes up as eth1 and the eth1 line is added to
/etc/udev/rules.d/70-persistent-net.rules
Almost as if there is something else that needs changing.
