Alright,
As this is a problem that does not only affect keepalived, but, all
cluster-like softwares dealing with aliases in any existing interface,
managed or not by systemd, I have tested the same test case in a
pacemaker based cluster, with 3 nodes, having 1 virtual IP + a lighttpd
instance runn

Based on comment #12, and other comments from other duplicate cases,
I'll summarize here in a better (and consolidated way) how to reproduce
the issue, how to mitigate it using the dummy workaround, and how to fix
it (with the backports/merge requests). At the end I might provide a PPA

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

The aforementioned link shows there's been work towards a fix in
systemd. Can't say if that suggests what can be done to improve
keepalived, but I've tagged this "server-next" to get it on the Ubuntu

It looks like there is some clear and actionable work in keepalived here
(even if as a workaround and the real fix ends up being in systemd), so
I'm marking it as Triaged.

If I understand the keepalived > 2.0.x behavior referred to by cdmiller
above (see 2019-03-07 comment) that is not the appropriate response to
the problem. Granted, it mitigates the consequences butr doesn't
address the underlying issue. A systemd-source issue should not cause
keepalived failover
