These have nothing to do with your problem.
dhcpcd is the source of your problem, in a way.

dhcpcd can run as a systemwide daemon, which tries to obtain DHCP lease
on any network interface barring "lo".
In stock configuration, dhcpcd will add IPv4LL (169.254/16) IP on a
interface if it fails to obtain a lease after 60 second timeout (IIRC).
And obviously you have no DHCP server on "ovs-system" :)
Debian's packaging of dhcpcd should prevent the daemon to obtain DHCP
lease on any interface that's listed in /etc/network/interfaces, but:

1) OVS bridge should not be listed there, it's dynamic by nature.
2) You're using Network Manager, so it's totally possible that you have
an empty /etc/network/interfaces, or no such file at all.


Long story short, consider running "systemctl mask dhcpcd" unless you
need dhcpcd to work in a way described above.


Another possible workaround is to add "noipv4ll" to dhcpcd.conf, but
this could break something else in your setup.
