Description Oleksandr Vorobiov 2016-10-26 14:47:47 UTC

Description of problem:


How to reproduce:
Try to deploy Openstack with OSPD, ipv6 and external loadbalancer. When deploying with ipv6 deployment fails with an error: 

-------------------------------------------------------
ssh: Could not resolve hostname [fd00:fd00:fd00:2000::250]: Name or service not known
--------------------------------------------------------

SSH tries to make a connection to the host with square brackets in the name and fails. Seems threr is a known issue and has been addressed already here:
