When the nova-compute start to running, the Service.start (nova/service.py) is invoked. Then, executes self.manager.init_host()， causing the exception (HostMappingNotFound) to accur. When I track the operation of function ComputeManager.init_host (nova/compute/manager.py), self._update_scheduler_instance_info is invoked, that is sending the RPC request to nova-scheduler to execute update_instance_info. I looked at the code nova-scheduler. the SchedulerManager.update_instance_info (nova/scheduler/manager.py) is invoked. Then, the self.driver.host_manager.update_instance_info is invoked. In the file nova/scheduler/host_manager.py, because of the host_name (xxx) is not in self._instance_info, self._recreate_instance_info will been invoked. Then, the self._get_instances_by_host can not get the instance from table host_mappings, the exceptions HostMappingNotFound is raised.
