[Bug 1819074] Re: Keepalived < 2.0.x in Ubuntu 18.04 LTS not compatible with systemd-networkd

[Bryce Harrington]

Oh, one other thing that will be necessary to file an SRU for this would
be a a series of "paint by number" steps to reproduce the issue, and to
verify the fix.  For example, something akin to:

Bug description:
  Systemd-networkd clobbers VIPs placed by other daemons on any
  reconfiguration triggering systemd-networkd restart (netplan apply for
  example).  Keepalived < version 2.0.x will not restore a VIP lost in
  this fashion, breaking high availability on Ubuntu 18.04 LTS.  A
  backport for keepalived >= 2.0.x should fix the issue.
