Change-Id: Idd108cbef944cdd89808bb1ad5c8ab1db202d31a Closes-Bug: #1846494 ** Changed in: neutron Status: In Progress => Fix Released -- You received this bug notification because you are a member of Yahoo! Engineering Team, which is subscribed to neutron. https://bugs.launchpad.net/bugs/1846494 Title: neutron-openvswitch-agent and IPv6 Status in neutron: Fix Released Bug description: I got two problems connected to IPv6 and neutron-openvswitch-agent (Queens version of Openstack, Ubuntu 18.04): The first problem: The default value of "of_listen_address" (setting in [ovs] section in file /etc/neutron/plugins/ml2/openvswitch_agent.ini) is 127.0.0.1. When I set it to its IPv6 equivalent "::1", it tries to pass that to ovs-vswitchd as "tcp:::1:6633", which is not valid URL according IPv6. As result ovs-vswitchd complains about that. When I set value to "[::1]" with idea the result to be valid URL "tcp:[::1]:6633", I got following exception: File "/usr/lib/python2.7/dist-packages/oslo_config/cfg.py", line 3378, in __getattr__ return self._conf._get(name, self._group) File "/usr/lib/python2.7/dist-packages/oslo_config/cfg.py", line 2940, in _get value = self._do_get(name, group, namespace) File "/usr/lib/python2.7/dist-packages/oslo_config/cfg.py", line 2983, in _do_get % (opt.name, str(ve))) oslo_config.cfg.ConfigFileValueError: Value for option of_listen_address is not valid: [::1] is not IPv4 or IPv6 address So the composing of URL with "of_listen_address" and "of_listen_port" for version IPv6 is not done correctly. The second problem: When I try to set "ovsdb_connection = tcp:[::1]:6640", again in "openvswitch_agent.ini", in logs I see neutron try to set manager as "ovs-vsctl set-manager ptcp::1]:6640:[". But I do not keep exact steps for reproduction. Also (just in case) I tried to set "ovsctl set-manager ptcp:6640:[::1]" , again in "openvswitch_agent.ini", but as expected I got follow error: ovs-vsctl[1957]: ovs|00001|vsctl|INFO|Called as /usr/bin/ovs-vsctl set-manager ptcp:6640:[::1] ovs-config.py[1962]: configobj.ParseError: Invalid line ('ovs-vsctl set-manager ptcp:6640:[::1]') (matched as neither section nor keyword) at line 58. So obviously it is for starting of server, not value for the ini file.
