gmann	kopecmartin: we covered most of the tests and we kept this to find and fix more tests but i have not seen network failure recently.	14:36
gmann	kopecmartin: we can close this and if something comes up then just fix it.	14:36
gmann	without this bug link or just with ref to bug	14:36

Title:
  [compute] "create_test_server" if networks is undefined and more than
  one network is present

Status in OpenStack Compute (nova):
  Triaged
Status in tempest:
  Fix Released

Bug description:
  This problem was detected in "ServersNegativeTestJSON" [1]. When a
  server is created ("cls.create_test_server"), if a network is not
  defined but several networks are present in this project, Nova raises
  the exception "NetworkAmbiguous", a seen in this log snippet:

  Sep 13 23:44:15.520980 ubuntu-bionic-limestone-regionone-0011283625 devstack@n-api.service[27339]: DEBUG nova.network.neutronv2.api [None req-c95ecec2-8d10-4984-8ba9-b608161dd645 tempest-ServersNegativeTestJSON-445859222 tempest-ServersNegativeTestJSON-445859222] validate_networks() for None {{(pid=27340) validate_networks /opt/stack/nova/nova/network/neutronv2/api.py:2251}}

  We can see that the network information provided to the server creation is empty but Nova tries to assign a default single network for this server. However Nova does not assign this default network because several networks are present for this project ID. In this case, the server creation should be specific passing the network information.
