Description

Observation

After starting arm-4/5 today (to investigate #109232) both workers were unable to get an IP address.

I couldn't find messages from them in /var/log/messages on qanet.qa.suse.de. I also couldn't ping it via arping:

openqaworker-arm-4:~ # arping -I eth0 -b 10.162.0.1
ARPING 10.162.0.1 from 10.0.2.2 eth0

There are no failed systemd units, including wicked. The network config looks like this:

openqaworker-arm-4:~ # ip addr

So eth0 is up. It looks exactly alike on arm-5.
