[Yaguang Tang]

172
173 def _build_instances(self, message, target_cells, instance_uuids,
174 build_inst_kwargs):
175 """Attempt to build instance(s) or send msg to child cell."""
176 ctxt = message.ctxt
177 instance_properties = build_inst_kwargs['instances'][0]
178 instance_type = build_inst_kwargs['instance_type']
179 image = build_inst_kwargs['image']
180 security_groups = build_inst_kwargs['security_group']
181 block_device_mapping = build_inst_kwargs['block_device_mapping']
182
183 LOG.debug(_("Building instances with routing_path=%(routing_path)s"),
184 {'routing_path': message.routing_path})
185

instance_type not in build_inst_kwargs dict.
security_groups should be get from build_inst_kwargs['security_groups']

the key error exception can cause schedule to child cell failed.
