Have the same root cause: the fact that systemd-network messes with secondary IP addresses in NICs managed by systemd.

I'm marking all other cases as a duplicate of LP: #1815101.

TODO here is the following:

- There are mainly 2 "fixes" for this issue:

1) keepalived is able to recognize systemd-networkd changes and change cluster status in order to reconfigure managed NICs (keepalived (> 2.0.x)).

2) systemd-networkd implements a new stanza (KeepConfiguration=) to systemd service unit files in order to fix not only this behavior but all those HA related software that manages secondary IPs and/or aliases to NICs being managed by systemd-networkd.

I think the most appropriate would make sure those 2 features work in Eoan, both, together, and then make sure the SRUs are done to Disco and Bionic. One problem w/ the item (2) is that netplan will also have to support the new "KeepConfiguration=" systemd service file stanza, but, the fix (2) is more appropriate for all other HA related softwares controlling virtual IPs (CTDB, Pacemaker, and so ...).
