Open Stack

Hello,

Same here, I will continue looking at this aswell.

Would be great if we could get some input from a neutron dev with good insight into the project.


Can we backtrace the timed out message from where it's thrown/returned.

Error: Request to https://127.0.0.1:9696/v2.0/floatingips/2e3fa334-d6ac-443c-b5ba-eeb521d6324c timed out', u'code': 400}

I'm interested why we would get 400 code back, the floating ip operations should be async right so this would be the response from the API layer with information from the database that should

return more information.


Best regards

Hey,
Do you know if the bug appears on a specific Ubuntu / openstack version?
As far as I remember it was not related to the puppet branch?  I mean the bug is existing on master but also on newton puppet branches, right?

We are using Ubuntu in my company so we would love to see that continue ;)
I'll try to take a look again.

Cheers.

Hi,

Hope that everyone had safe travels and enjoyed their time at Sydney
(and those who weren't there enjoyed a bit of quiet time!).  I'm just
sending this email if anyone had a chance to look more into this (or
perhaps we can get some help if there are any Canonical folks on the
list?)

I would be really sad if we had to drop Ubuntu/Debian support because
we cannot test it.  I think there are a lot of users out there using
it!  I'd be more than happy to provide any assistance/information in
troubleshooting this.

Thank you,
Mohammed
