After watching it carefully, I found two problems: 1, compute node should set hostname, or ovs process will exit due to below error log Stderr: 'sudo: unable to resolve host juju-precise-machine-11\n2015-01-04T06:41:49Z|00001|fatal_signal|WARN|terminating with signal 14 (Alarm clock)\n'
2, also should restart ovs process after rescheduling the l3-agent, or ovs will not create the tunnel again. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1405588 Title: database connection failed (Protocol error) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/openvswitch/+bug/1405588/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
