Open Stack

I'm trying to create new instance and it has been failing with the
following stack - failed to get network information.


- build_and_run_instance is called.

-locked_do_build_and_run_instance is called to get resources.

-Memory, disk space resource claim is successful.

- Then, trying to build network resource asynchronously: _allocat
e_network_async


The issue is started.  I found that message has been sent but response is
not received.  Can anyone suggest me what logs should I look into to see
what is happening in response?  Why is it timed out?  How to debug it
further?  Any issue with nova.conf that I may be missing?
