Hi Akihiro, I have a question about the deletion of network. when there're some ports has been created and attached to the network, can you be able to delete the network and all its ports? I test this operation and got "QuantumClientexception:unable to complete opertion on network. There is one or more attachments plugged into its ports". The error web page is dumped with these detail exception messages. is it a correct behavior?
