In the undercloud machine you can find under /home/stack/overcloud_deploy.sh the overcloud's deployment script.
Or and myself looked at this issue and it seems like there was a problem with the DB creation during the installation process.
So in a similar concept to the what happens in the devstack plugin, it seems like it tried to populate the database but it never got created.
Or, please check and report how we can get more details here (debug level logs etc). we need to understand why that DB never got created.
Could you please let me know hen you have the setup deployed inorder to verify this bug ?
