thanks
i move the controller to the subnet with ovs, and it works
but there' still a problem like this:
File
"/usr/local/lib/python2.7/dist-packages/ryu/services/protocols/ovsdb/client.py",
line 212, in __init__
self.readonly = schema.readonly
AttributeError: 'DbSchema' object has no attribute 'readonly'
so, i find the attribute readonly is useless, i comment this line...
up to now, the connection between ovs and controllor using ovsdb protocol
is established
thank you again
