@PCM Could you provide a patch with the files so we could patch it into a local
repo and try things? I’m assuming since it is an experiment with no functional
code that maybe there’s nothing proprietary? :)

@PCM Hmmm… Just a wild guess... I’m wondering if this is the issue. You class
would need to inherit from the base device driver class. Does your
fake_device_driver.py have the correct import paths? I say that, because your
hierarchy is different. For example, the layout currently is…
neutron/services/vpn/ - plugin
neutron/services/vpn/device_drivers/ - reference and Cisco device drivers
neutron/services/vpn/service_drivers/ - reference and Cisco service drivers
Your hierarchy has another level…
neutron/services/vpn/junos_vpnaas/device_drivers/
I’m wondering if there is some import wrong. For example, the reference device
driver has:
from neutron.services.vpn import device_drivers
…
@six.add_metaclass(abc.ABCMeta)
class IPsecDriver(device_drivers.DeviceDriver):
"""VPN Device Driver for IPSec.
Where the import is used to access the base class DeviceDriver. If you’re doing
the same, that file may be failing to load.
