Engineering Team, which is subscribed to OpenStack Compute (nova). https://bugs.launchpad.net/bugs/1711303 Title: Filter instances by IP when listing is not efficient enough Status in OpenStack Compute (nova): Fix Released Bug description: Filtering instance by IP when listing is done by: http://git.openstack.org/cgit/openstack/nova/tree/nova/compute/api.py#n2457 this is due to that IP address is one part of the instance.network_info JSON, we have to iterate one by one to find the instance that matches the request. This is actually not efficient enough, on our public cloud deployment, one Enterprise user could own over 1000 instances and when they filter by IP, HTTP 500 timeout raised. We might consider improve the implementation.
