Thanks. So notably, *none* of the entries in your 70-persistent-net.rules matches the original ethernet device. This explains why, on reboot, the eth0 name was not reserved for the device that was used at install time.

Looking at /lib/udev/rules.d/75-persistent-net-generator.rules, it appears that the hardware address "16:59:c0:50:0a:02" matches this line:

ENV{MATCHADDR}=="?[2367abef]:*", ENV{MATCHADDR}=""

The comment preceding this line is:

# ignore interfaces with locally administered or null MAC addresses
# and VMWare, Hyper-V, KVM, Virtualbox and Xen virtual interfaces

And a bit of research shows that, indeed, this mac address of 16:[...] has the bit set that indicates a locally-administered address.

Is this pre-production hardware? Or is it expected that partitions under PowerVM use locally-administered mac addresses?
