We are the team that manages the developer infrastructure for building openstack the software, but don't have much experience running openstack directly ourselves. You may have better luck with this request sending it to openstack-discuss at lists.openstack.org which is the general openstack list and has developers, operators, and users subscribed to it.

The above having been said the problem appears to be that the address is already in use. You should check netstat or ss to see what is listening on tcp port 8775 and kill that before starting the service again.
