Comment 6 for bug 1856152

Hello zhangyuhe:

The problem is not exactly in this method but in in the upper one [1]. You stated that you are using Pike, quite old version. But this method is missing [2]; this patch is adding the integration bridge name configured in OVS.integration_bridge (default value "br-int") in the vif details.

There is the problem you are facing: the vif details passed to Nova do not have the overwritten value you manually defined.

Please, try to import to your code this patch or update to a newer version. [2] is present in master, Train and Stein.

Regards.
