Hello,

We are trying to deploy mistral with IPV6 (Keystone is IPV6, the VM that we are installing on is IPV6 too, all OS Endpoints IPV6) – by changing In the ‘mistral.conf’ -> ‘bind_host=::’ .
In Murano it was working pretty straight forward by changing this param.. but unfortanly for now for Mistral not.

A little but searching in the internet we found this for Ceilometer : https://bugs.launchpad.net/ceilometer/+bug/1269243 maybe same implementation needed here too.

So we are wondering If in high level if Mistral can support IPV6 and if someone can advise here ?

This is the exception when we are trying to start the mistral with ‘bind_host=::’
