I think You are missing initialization for running period tasks. You need prepare a daemon service with period tasks like nova-compute There are some key points to enable period task: 1. add period tasks to thread group https://github.com/openstack/nova/blob/master/nova/service.py#L194 2. make manager class inherit from periodic_task.PeriodicTasks https://github.com/openstack/nova/blob/master/nova/manager.py#L91 3. run service as daemon https://github.com/openstack/nova/blob/master/nova/cmd/compute.py#L56 2017-08-14 17:50 GMT+08:00 zhi <changzhi1990 at gmail.com>: > Hi, all. > > There are two ways to run period tasks in OpenStack.
