[Bug 1481337] [NEW] keepalived makes a floating IP available on more than one host after configuration reload

[Launchpad Bug Tracker]

The version in 14.04 is 1:1.2.7-1ubuntu1

There's an issue with reloading the configuration file, where the state
of VRRP gets 'confused' (in lack of a better description), resulting in
a floating IP being available on more than one host.

This issue seems to be fixed in 1.2.17. Since the package hasn't had an
update in over 2 years, I kindly request it to be updated to at least
1.2.17

For more information, see http://www.keepalived.org/changelog.html

Extra info:
1) The release of Ubuntu you are using, via 'lsb_release -rd' or System -> About Ubuntu

Description:	Ubuntu 14.04.2 LTS
Release:	14.04

2) The version of the package you are using, via 'apt-cache policy
pkgname' or by checking in Software Center

1:1.2.7-1ubuntu1

3) What you expected to happen

Keepalived config reloaded without interruption of services. VRRP should
notice VIP being present on one host and do nothing.

4) What happened instead

Keepalived config was reloaded but VRRP decided to activate the VIP on
the host that didn't have it previously. Resulting in routing errors
etc.
