Ran this on the latest release of Server 2016, then installed 2012 R2 and got the same thing. Looks like it bombs out after the following:
2016-09-30 11:18:52,552 DEBUG logging debug 1630 4728 AsyncLoopThread OpenStack config: {'oslo_messaging_rabbit': {'rabbit_hosts': '', 'rabbit_userid': '', 'rabbit_password': ''}, 'glance': {'api_servers': ''}, 'keystone_authtoken': {'admin_tenant_name': '', 'admin_password': '', 'admin_user': ''}, 'neutron': {'username': '', 'project_name': '', 'url': '', 'user_domain_name': '', 'auth_url': '', 'password': '', 'project_domain_name': ''}}

Here's the rest of the log: http://pastebin.com/L9ZZuxj0 console log: http://pastebin.com/CM5Aq4Gp Prior to this, CentOS rebooted after installing the Linux Integration Services. It fails after the exact same event in both 2012R2 and 2016.
