Nova metadata should bind to 0.0.0.0 instead of 127.0.0.1 #16

Closed fmanco closed 11 years ago

fmanco commented 11 years ago

Please anyone can confirm this is necessary.

I have a setup that only works this way and other that works fine without this. Any clues?

bilelmsekni commented 11 years ago

If you have one working fine without it, it means that it is not necessary ! Logically speaking, it should be binded to 0.0.0.0 if it's a multinode install (and 127.0.0.1 if it's a single node install)

I will investigate this further more and thank you for your contribution :)

Found the problem. I completely forgot that on the setup that is failing I am also run nova-compute on the controller node. That's why I need to bind to 0.0.0.0. On the controller node 127.0.0.1 is fine.

And on the compute node ? Does it need to bind to 0.0.0.0 ?

My last comment is wrong. I should have tested this a little further before comment, sory.

Now I tested this with the following setup

The one that needs to bind to 0.0.0.0 is the controller node. That's because (AFAIK) the quantum metadata agent on the network node needs to connect to the nova metadata server on the controller node. For the compute node it doesn't really matter because if you check the LISTEN sockets you don't see any on 8775.

So I think you can in fact merge my pull request.

Can you please correct things out and send the merge request. Once you have closed it it's gone actually :)
