floatingip not found 404 PecanNotFound

[Iago Santos]

I am seeing this error often on Neutron side, I am not using floatingips, even blocking the action in the policies doesn't fix the issue neither.

WARNING neutron.pecan_wsgi.controllers.root [req user id - default default] No controller found for: floatingips - returning response code 404: PecanNotFound

Possible patch but in Nova: https://github.com/openstack/nova/blob/master/nova/network/neutronv2/api.py#L2155

What actions do you perform to trigger this log trace? None? What version of neutron are you using?

I am running Queens release, when I ask for floating ips running openstack floating ip list or create, I see this warning coming to my server, as I mentioned before, I tried to block the policy to not allow users to ask for this, anyway even blocking it in the policy it comes to me this warning, the only way I managed to remove this warning was patching the code in Nova, actually I don't really think it is a good practice, I would like to hear your opinion.

Thanks for file this bug. But it's strange as you said. If you run osc cmd: openstack floating ip list or create, the request will look up the neutron endpoint. And as you said, you patch the code in nova, sounds like the WARNING log could be found in Nova compute. Right? So you said you found in server log.

Could u please run the cmd with --debug? And show us the debug info, it's also good to show the server configuration.

Here is the info from running openstack floating ip list --debug: https://pastebin.com/LVM6Wq6W
And the neutron server.log where I see the warning: https://pastebin.com/YpiVDspc

Patching the code in Nova I got rid of the warning in neutron server, in nova logs I don't see anything about this.

Thanks,

Have you enable the L3 service plugin in neutron.conf?

[DEFAULT]
service_plugins = neutron.services.l3_router.l3_router_plugin.L3RouterPlugin/router

[Iago Santos (isantospa)]

Not now, I tried before, but by default I don't want to have enable the creation of routers, thats why I have removed it. What is the best practice to follow?

[YAMAMOTO Takashi (yamamoto)]

if you don't have the router service plugin configured, it seems like a normal behaviour to me. what exactly do you think a problem?
