Hi Doug, Thank you very much for your reply. I don't have any codes, so no any special codes as well. Only thing I did is that: 1, use devstack to install a fresh openstack env, all are ok. 2, import neutron-vpnaas directory (no any my own codes) into eclipse as pydev project, for example, run unit test (neutron_vpnaas.tests.unit.services.vpn.test_vpn_service ) in eclipse, it throws the following exception. 3, but this unit test can be run well in bash, see http://paste.openstack.org/show/172016/ 4, this unit test can also be run well in eclipse as long as I edit neutron/openstack/common/policy.py file to change oslo.config into oslo_config.
