<div dir="ltr"><div>I worked on bug [1] and pushed change request [2] and I got Ryu CI check failing [5], because flat_networks is not set in config. For vlan networks empty list in 'network_vlan_ranges' means that no physical networks are allowed [3], for flat networks there is only help string for config option [4] and it seems that similar behaviour is expected there too. So, my question is what should be done in this case?  Should default be changed to '*' or should some changes be done on devstack side?<br><div><div><br></div><div>[1] - <a href="https://bugs.launchpad.net/neutron/+bug/1424548">https://bugs.launchpad.net/neutron/+bug/1424548</a></div><div>[2] - <a href="https://review.openstack.org/160842">https://review.openstack.org/160842</a></div><div>[3] - <a href="https://github.com/openstack/neutron/blob/master/neutron/plugins/ml2/drivers/type_vlan.py#L175">https://github.com/openstack/neutron/blob/master/neutron/plugins/ml2/drivers/type_vlan.py#L175</a><br></div><div>[4] - <a href="https://github.com/openstack/neutron/blob/master/neutron/plugins/ml2/drivers/type_flat.py#L32">https://github.com/openstack/neutron/blob/master/neutron/plugins/ml2/drivers/type_flat.py#L32</a></div></div></div><div>[5] - <a href="http://180.37.183.32/ryuci/42/160842/5/check/check-tempest-dsvm-ofagent/005e5e2/logs/devstacklog.txt.gz">http://180.37.183.32/ryuci/42/160842/5/check/check-tempest-dsvm-ofagent/005e5e2/logs/devstacklog.txt.gz</a></div></div>
