Comment 5 for bug 1788185

After some checks it looks for me that reason of issue is in "broken" keepalived package. In master branch version "1:1.3.9-1ubuntu0.18.04.1~cloud0" is used and this one works fine. In Queens, Pike and Ocata patches it uses version "1:1.2.24-1ubuntu0.16.04.1" which seems to be broken and which removes all IP addresses from qr-XXX interface during spawning process.
I checked locally that versions older and newer than 1:1.2.24-1ubuntu0.16.04.1 works fine and on this one version there is this issue every time.
