After install all the nova services, all seem to be running fine, except for nova-api. I even reboot my controller node, no luck. After reboot all services are running, except nova-api. When I manually start nova-api, nova-api crashes with the following error "<b>error: [Errno 98] Address already in use</b>". I installed nova-volume earlier during the install process, but later on installed cinder, and made the necessary modifications (as far as I can tell) to nova-api.conf to use cinder for block storage. Should I uninstall nova-volume? </div><div><br></div><div><div>2012-11-12 14:46:24 INFO keystone.middleware.auth_token [-] Starting keystone auth_token middleware</div><div>2012-11-12 14:46:24 INFO keystone.middleware.auth_token [-] Using /var/lib/nova/keystone-signing as cache directory for signing certificate</div><div>2012-11-12 14:46:24 CRITICAL nova [-] [Errno 98] Address already in use</div><div>2012-11-12 14:46:24 TRACE nova Traceback (most recent call last):</div><div>2012-11-12 14:46:24 TRACE nova File "/usr/bin/nova-api", line 50, in <module></div><div>2012-11-12 14:46:24 TRACE nova server = service.WSGIService(api)</div><div>2012-11-12 14:46:24 TRACE nova File "/usr/lib/python2.7/dist-packages/nova/service.py", line 584, in __init__</div><div>2012-11-12 14:46:24 TRACE nova port=self.port)</div><div>2012-11-12 14:46:24 TRACE nova File "/usr/lib/python2.7/dist-packages/nova/wsgi.py", line 72, in __init__</div><div>2012-11-12 14:46:24 TRACE nova self._socket = eventlet.listen((host, port), backlog=backlog)</div><div>2012-11-12 14:46:24 TRACE nova File "/usr/lib/python2.7/dist-packages/eventlet/convenience.py", line 38, in listen</div><div>2012-11-12 14:46:24 TRACE nova sock.bind(addr)</div><div>2012-11-12 14:46:24 TRACE nova File "/usr/lib/python2.7/socket.py", line 224, in meth</div><div>2012-11-12 14:46:24 TRACE nova return getattr(self._sock,name)(*args)</div><div>2012-11-12 14:46:24 TRACE nova error: [Errno 98] Address already in use</div><div>2012-11-12 14:46:24 TRACE nova </div><div>2012-11-12 14:46:24 INFO nova.service [-] Parent process has died unexpectedly, exiting</div><div>2012-11-12 14:46:24 INFO nova.service [-] Parent process has died unexpectedly, exiting</div><div>2012-11-12 14:46:24 INFO nova.wsgi [-] Stopping WSGI server.</div><div>2012-11-12 14:46:24 INFO nova.wsgi [-] Stopping WSGI server.</div></div><div><br></div><div>Would highly appreciate any pointers to understanding or resolving the issue. </div><div><br></div><div>Regards,</div><div>Ahmed.</div><div><br></div><div><br></div><span id="OLK_SRC_BODY_SECTION"><div style="font-family:Calibri;
