This looks like the cloud configures Openvswitch, although it is not deployed. Perhaps deployment is incomplete only on the node where the instance is scheduled.

Does this happen only once or all the time? How was this cloud created? What is its Neutron and ML2 configuration?

This error is generated by function _plug_os_vif() in https://opendev.org/openstack/nova/sr..., itself called by plug(). Setting the log level to DEBUG should print more information about this problem.

devstack deploy base on https://docs.openstack.org/devstack/latest/guides/neutron.html%EF%BC%8CI've (https://docs.openstack.org/devstack/l...) tried many times, the error is repeated.

So my third question remains: What is its Neutron and ML2 configuration? You could also add the local.conf to your question.

Why don't you use the official devstack repo? This is the third time I see somebody with problems when cloning trystack.cn.
