Comment 4 for bug 1741291

Hi mhhli,

Thanks for providing the detailed information. A few observations:

* Your log suggested you were using API version 1.4
* The kolla image name suggested you were using the Pike release (which is consistent with API version 1.4)

Then, it looks your Zun version is too old. The v4-fixed-ip support was landed after the pike release: https://review.openstack.org/#/c/504308/ . I think the issue will be fixed if you try a newer version of kolla image. If it doesn't work for you, I can try to work with kolla team to backport the v4-fixed-ip support to Pike.
