Public bug reported: We're getting the following error in the gate on linux bridge jobs:
2017-03-16 15:13:15.984 5903 ERROR oslo_messaging.rpc.server libvirtError: Unable to add bridge brq776c3f9c-e6 port tapc5c67a59-f3: Device or resource busy This is caused by the merge of I2a23d0cbc4c4d0db6e9f48d91ca03b5007f91a84 which causes the LB agent to no longer skip compute ports. Even though os-vif has protection from races, it appears that libvirt itself is not robust to the tap being added to the bridge by another process. 1. http://logs.openstack.org/06/445706/5/gate/gate-tempest-dsvm-neutron- linuxbridge-ubuntu-xenial/a1314ac/logs/screen-n-cpu.txt.gz?level=TRACE ** Affects: neutron Importance: High Assignee: Kevin Benton (kevinbenton) Status: New ** Tags: gate-failure ** Changed in: neutron Assignee: (unassigned) => Kevin Benton (kevinbenton) ** Tags added: gate-failure ** Changed in: neutron Importance: Undecided => High -- You received this bug notification because you are a member of Yahoo!
