Bug Description

I'm trying to create a magnum cluster on Devstack(both Queens and master). Cluster creation is failing.

Nova Instance is going to error state with the below error:

{"message": "'NoneType' object has no attribute 'hosts'", "code": 500, "details": " File
\"/opt/stack/nova/nova/conductor/manager.py\", line 585, in build_instances
     instance_uuids,
 return_alternates=True)
   File \"/opt/stack/nova/nova/conductor/manager.py\", line 720, in
 _schedule_instances
     scheduler_utils.setup_instance_group(context, request_spec)
   File
 \"/opt/stack/nova/nova/scheduler/utils.py\", line 836, in setup_instance_group

 request_spec.instance_group.hosts = list(group_info.hosts)
 ", "created": "2018-08-10T08:32:01Z"}

Getting this error http://paste.openstack.org/show/727798/ in nova-cell-region and http://paste.openstack.org/show/727799/ in nova-cell-child
