There is an exception in /lib/udev/rules.d/75-persistent-net-generator.rules
for ibmveth:
# ibmveth interfaces have stable locally administered MAC addresses
SUBSYSTEMS=="ibmveth", ENV{MATCHADDR}="$attr{address}"
This should override the issue related to locally administered mac
addresses in this case. However, if we run:
udevadm monitor --e
and then:
echo "add" > /sys/class/net/eth0/uevent
We see:
KERNEL[622.903561] add /devices/vio/30000002/net/eth0 (net)

If I make this change to /lib/udev/rules.d/75-persistent-net-
generator.rules, then I get a rule generated for ibmveth devices:
