Hugo, do you have the server side traces? from nova api logs?

thanks,

sorry,i can not find any logs from the server includeing nova logs, keystone logs, neutron logs and so on.
i tried to use the reboot method of ServerApi, and it is ok.
so i tried to debug the resize method, i found the request have not authentication.
why running the resize method is not success,but running other methods of ServerApi are ok?

it seems that the http header validate failed.so there are no any logs.
i encapsulate this interface by httpclient.now it works well.
and i want to report anthor bug.
thanks
