Public bug reported: I followed the procedure from https://docs.openstack.org/ocata/install- guide-ubuntu/InstallGuide.pdf to build OpenStack environment.
But while launching instance I got the error as follows; Unexpected API Error. Please report this at http://bugs.launchpad.net/nova/ and attach the Nova API log if possible. <class 'sqlalchemy.exc.OperationalError'> (HTTP 500) (Request-ID: req-d6a9eec9-0570-4844-9434-d85d04c52883) After getting this error, I made a new database for Nova but it is using the old database and giving the same error.
