Public bug reported:
Description:
Neutron is installed by means of Helm into dedicated containers,
i.e. neutron-api under Apache mod_wsgi and rpc-server as an eventlet process.
For debug purpose one replica was set for these services.
Run of
tempest.api.compute.servers.test_attach_interfaces.AttachInterfacesUnderV243Test.test_add_remove_fixed_ip
throws exception (not 100% reproducible but very often):
Traceback (most recent call last):
File
"/var/lib/openstack/lib/python3.6/site-packages/tempest/common/utils/__init__.py",
line 89, in wrapper
return f(*func_args, **func_kwargs)
File
"/var/lib/openstack/lib/python3.6/site-packages/tempest/api/compute/servers/test_attach_interfaces.py",
line 366, in test_add_remove_fixed_ip
'Timed out while waiting for IP count to increase.')
tempest.lib.exceptions.TimeoutException: Request timed out
Details: Timed out while waiting for IP count to increase.
Debugging reveals the os_primary.servers_client.list_addresses() function gets
updates with some delay ~3-5sec, therefore original_ip_count variable is
setting to the incorrect value [1].
There is no such behaviour under classic neutron-server process.
Version:
* OpenStack version is Stein (neutron 14.0.4.dev52 build from stable/stein)
* Ubuntu 18.04.2 LTS
