Comment 14 for bug 1846198

Yes, patch pointed by Brian my definitely fix this issue.
I tried it on single node devstack but with router created as HA. So it spawned keepalived process and created HA interface like in "regular" HA case. The only difference was that there was no second host with keepalived in same "cluster" so failover couldn't happend. I did it like that because I wanted to check if there is no any flap of HA interface or keepalived process during agent restart.
