The issue is present if you're running 2 or more nodes with a keepalived < 1.2.8. This bumps the version of keepalived role (installing a more recent version of keepalived by default) AND edits the keepalived configuration file to avoid having nodes with the same priority. This will restart your keepalived service. Please note this commit is not meant for backporting. The deployer running on mitaka and below should follow the documentation here: https://review.openstack.org/#/c/279664/ Bug: #1545066 Change-Id: Ie28d2d3fa8670212c64ecbdf5a87314e7ca0a2d9
