Doc Text:
Previously, the lbaasv2 stevedore entry point was not registered in the neutron.service_plugins namespace. This would cause neutron-server to fail if the lbaasv2 alias was used in the service_plugins option instead of the full Python import path to the plug-in. With this update, the missing stevedore alias was added to the package, allowing neutron-server to load the lbaasv2 plug-in using the alias.

I imagine there's been an upstream stable/liberty release since January. We should rebase and release an updated OSP 8. Can you please chase this down with Nir?
Comment 6 Ihar Hrachyshka 2016-06-07 12:08:08 UTC 
Assaf, we should solve the issue of rebases not happening in OSP irrespective to the bug.

As for the bug itself, our latest releases for OSP8 include the patch, since we base on 7.0.4.
Comment 8 Toni Freger 2016-06-27 15:48:04 UTC 
neutron conf with below configuration restarted well.
neutron.conf 
# service_plugins =
service_plugins =router,lbaasv2 
(tested on openstack-neutron-7.0.4-7.el7ost.noarch)
