How did you install OpenStack? If it's Packstack, these instructions indicate it's possible.

Generally, changing addresses requires changes in the depth of OpenStack's databases and is therefore not supported. Here is somebody who seems to have managed this on a Devstack cloud - but over four years ago. This means that your database schema is likely to be different than his.
