Re: [Rdo-list] Icehouse multi-node - Centos7 - live migration failed because of "network qbr no such device"

----- File "/usr/lib/python2.7/site-packages/neutronclient/client.py", line 239, in authenticate\\n content_type="application/json")\\n\', u\' File "/usr/lib/python2.7/site-packages/neutronclient/client.py", line 163, in _cs_request\\n raise exceptions.Unauthorized(message=body)\\n\', u\'Unauthorized: {"error": {"message": "The request you have made requires authentication.", "code": 401, "title": "Unauthorized"}}\\n\'].\n'] ----- Looks like HTTP connection to neutron server is resulting in 401 error. Try enabling debug mode for neutron server and then tail /var/log/neutron/server.log , hopefully you should get more info.
