This sounds more like a Neutron problem then a Heat problem. Could you attach the template you used, so we can investigate if the correct component is openstack-heat or openstack-neutron? Created attachment 858760 [details]
template + script
Added a script and template. I deploy the public network and subnet manually via Neutron commands. Then I deploy the router, private net, private subnet, Cinder volume, floating IP, and instances via a HOT template. Could you include the exact steps you use the launch the instance including the creation of the public network and subnet? You can use the "script" command to record the operations you perform, and type exit to save it to the file "typescript". Regards, -steve Created attachment 862999 [details]
Command output to reproduce
Steve Baker, Could you verify my logic before I bump this bug to neutron? Based upon this log information from Comment #7: [root@rhos1 bz1064889(refarch_member)]# ssh rhos6 ip netns Warning: Permanently added 'rhos6,10.16.137.106' (RSA) to the list of known hosts. root@rhos6's password: qdhcp-53f673eb-a147-49aa-b590-beba2ec561b7 qrouter-96eb702a-bf57-408a-bf1f-3a9521481a43 And the fact that inspecting the code at: https://github.com/openstack/heat/blob/stable/havana/heat/engine/resources/neutron/router.py#L62 shows the delete path, this looks like a netns leak in Neutron or one of its dependencies. Would you concur? Given that heat is not aware of the network namespaces this appears to be a neutron bug. I have reassigned the component. It is a configuration in Neutron if to delete the namespace or not. The default is not to delete the name space, configuration values - dhcp-agent: ----------- dhcp_delete_namespaces = False l3-agent: --------- router_delete_namespaces = False This is turned off because of some issue we saw in RHEL 6.
