Linuxbridge agent failed to create some bridges after the os was rebooted

[Lan Qi song]

When I rebooted the operation system which hosted the Linuxbridge agent , Linuxbridge agent will try to recreate all the bridges according to the updated tap devices.

But I have found that some bridge were not created, and I found the weird log message:

In l3-agent.log: The tap device seems already created at 2015-10-27 00:53:15

2015-10-27 00:53:15.002 5135 DEBUG neutron.agent.linux.utils [-] Running command: ['sudo', '/usr/bin/neutron-rootwrap', '/etc/neutron/rootwrap.conf', 'ip', 'link', 'add', 'tap5f17438b-6e', 'type', 'veth', 'peer', 'name', 'qr-5f17438b-6e', 'netns', 'qrouter-f3f17112-aadc-4649-9662-6bf25cad569d'] create_process /usr/lib/python2.7/dist-packages/neutron/agent/linux/utils.py:84

But in linuxbridge-agent.log: the linuxbridge agent think the tap device was not created yet and give up to create the related bridge at 2015-10-27 00:53:27
