Engineering Team, which is subscribed to OpenStack Compute (nova). https://bugs.launchpad.net/bugs/1747167 Title: Neutron driver handles incorrectly 404 errors Status in OpenStack Compute (nova): Fix Released Bug description: Neutronclient transforms errors using exception_handler_v20[1]. In particular, it transforms 404 responses into: 1) [2] neutronclient.common.exceptions.<type>Client if response body contains a type attribute (with value <type>, type examples: NetworkNotFound, PortNotFound) and <type>Client exists 2) [3] neutronclient.common.NotFound otherwise Nova neutron driver[4] supports mostly 1) but not 2). But Neutron in case of 404 returns the following body: {"message": "The resource could not be found.<br /><br />\n\n\n", "code": "404 Not Found", "title": "Not Found"} and we end in 2) and Nova Neutron driver doesn't catch the error correctly and raises a 500 You can reproduce it indirectly using: openstack server add fixed ip <vm> <network-name> which queries: nova-base-url/os-networks/<network-name> assuming it would return the network or a 404 but it returns 500. This trouble can be solved by catching NotFound instead of NetworkNotFoundClient/PortNotFoundClient as there are subclasses of NotFound.
