Keepalived v1.3.5 failing to assign IP for HA interface

[venkata anil]

From the below syslog, I see keepalived is unable to read IP address from config filr to configure HA interface(though config file is properly configured). Need to check why this is happening. I also tested Keepalived v1.3.5 on ubuntu machine and saw the same error.

Steps to reproduce:
Install Keepalived v1.3.5 and run below functional test
neutron.tests.functional.sanity.test_sanity.SanityTestCaseRoot.test_keepalived_ipv6_support
This test will fail and you can see the errors in syslog.

    Fix test_keepalived_ipv6_support for Keepalived v1.2.20

    In commit [1] (some explanation in [2] ) VRRP initialisation is enhanced
    to read source IP address(to use when sending VRRP packets) from the
    HA interface or from keepalived config("unicast_src_ip" parameter).
    If it is unable to find IP address, VRRP initialisation will fail with
    error "Cannot find an IP address to use for interface".

    In the test, we set vrrp->family to AF_INET by setting vip to
    169.254.0.1/24 through config, but not providing source IPv4 address(i.e
    no 'unicast_src_ip' option or no IP on HA interface), making the test
    to fail with [1]. To fix that, we set the IP address on HA interface.

    Note: Commit [1] is added in Keepalived version 1.2.20.
    Tested the fix on both Keepalived v1.2.19 and Keepalived v1.2.20.

I am using ussuri OpenStack but keepalive doesn't assign IP for HA interface?
