Public bug reported: Hi,
I'm running queens on xenial. The following commit introduced a regression : https://git.openstack.org/cgit/openstack/neutron/commit/?id=2b1d413ee90dfe2e9ae41c35ab37253df53fc6cd (fixing bug 1767422) The following call is wrong (in router_info.py) : self.driver.remove_vlan_tag(self.agent_conf.external_network_bridge, interface_name) In this call, interface_name is something like "qg-abcdefg-12", but remove_vlan_tag() expects a tap interface. This results in the following log : 2018-10-24 00:28:40.880 23623 DEBUG ovsdbapp.backend.ovs_idl.transaction [-] Running txn command(idx=0): DbClearCommand(column=tag, table=Port, record=qg-0410dbf1-51) do_commit /usr/lib/python2.7/dist-packages/ovsdbapp/backend/ovs_idl/transaction.py:84 2018-10-24 00:28:40.881 23623 DEBUG ovsdbapp.backend.ovs_idl.transaction [-] Transaction aborted do_commit /usr/lib/python2.7/dist-packages/ovsdbapp/backend/ovs_idl/transaction.py:112 Sadly, the cause of the "Transaction aborted" is hidden (in https://github.com/openstack/ovsdbapp/blob/master/ovsdbapp/backend/ovs_idl/transaction.py#L87). If I print the exception, I get the following : 2018-10-24 00:28:40.881 23623 DEBUG ovsdbapp.backend.ovs_idl.transaction [-] EXCEPTION Cannot find Port with name=qg-0410dbf1-51 do_commit /usr/lib/python2.7/dist- packages/ovsdbapp/backend/ovs_idl/transaction.py:88 Checking the ovs database reveals that Port "names" are the tap interfaces, not the qg- interfaces. The ports staying the VLAN 4095 will basically make the network unusable. Using the following call fixes my problem : self.driver.remove_vlan_tag(self.agent_conf.external_network_bridge, self.driver._get_tap_name(interface_name,prefix=EXTERNAL_DEV_PREFIX)) It would be nice to print the exception caught in https://github.com/openstack/ovsdbapp/blob/master/ovsdbapp/backend/ovs_idl/transaction.py#L87 by the way... Thanks !
