[Bug 1268274] Re: KeyError in _get_server_ip

  Thread Previous • Date Previous • • Thread Next 
I think this fails because when the server boots up, a call to Nova to
show the Server details returns no network information:

Looking at the nova-api log, it shows that the cache is updated with
empty values:
