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 "error: [Errno 98] Address already in use". 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? 2012-11-12 14:46:24 INFO keystone.middleware.auth_token [-] Starting keystone auth_token middleware 2012-11-12 14:46:24 INFO keystone.middleware.auth_token [-] Using /var/lib/nova/keystone-signing as cache directory for signing certificate 2012-11-12 14:46:24 CRITICAL nova [-] [Errno 98] Address already in use 2012-11-12 14:46:24 TRACE nova Traceback (most recent call last): 2012-11-12 14:46:24 TRACE nova File "/usr/bin/nova-api", line 50, in <module> 2012-11-12 14:46:24 TRACE nova server = service.WSGIService(api) 2012-11-12 14:46:24 TRACE nova File "/usr/lib/python2.7/dist-packages/nova/service.py", line 584, in __init__ 2012-11-12 14:46:24 TRACE nova port=self.port) 2012-11-12 14:46:24 TRACE nova File "/usr/lib/python2.7/dist-packages/nova/wsgi.py", line 72, in __init__ 2012-11-12 14:46:24 TRACE nova self._socket = eventlet.listen((host, port), backlog=backlog) 2012-11-12 14:46:24 TRACE nova File "/usr/lib/python2.7/dist-packages/eventlet/convenience.py", line 38, in listen 2012-11-12 14:46:24 TRACE nova sock.bind(addr) 2012-11-12 14:46:24 TRACE nova File "/usr/lib/python2.7/socket.py", line 224, in meth 2012-11-12 14:46:24 TRACE nova return getattr(self._sock,name)(*args) 2012-11-12 14:46:24 TRACE nova error: [Errno 98] Address already in use 2012-11-12 14:46:24 TRACE nova 2012-11-12 14:46:24 INFO nova.service [-] Parent process has died unexpectedly, exiting 2012-11-12 14:46:24 INFO nova.service [-] Parent process has died unexpectedly, exiting 2012-11-12 14:46:24 INFO nova.wsgi [-] Stopping WSGI server. 2012-11-12 14:46:24 INFO nova.wsgi [-] Stopping WSGI server.

No that is it. Are you sure a) you don't have another nova-api or nova-metadata or nova-api-os-compute process running? and b) that your nova.conf is being read properly?

BTW, as mentioned earlier nova-volume and cinder-volume using the same port is NOT a bug, it's by design. Also there seems to be some confusion here, osapi_compute does NOT use 8776, it uses 8774 by default. Something that was pointed out earlier today is that the install document lists everything under the keystone ini heading. If you copied your nova.conf exactly like the doc then your entry for: enabled_apis=ec2,osapi_compute,metadata Is going to be ignored. Would you please provide your nova.conf and cinder.conf files (link to a pastebin perhaps), and we can verify this. John Hi John, When you say I still have nova-volume configured, do you mean it is still running on my controller node. I don't think nova-volume is running (from output of "ps aux | nova"), but I could be wrong. However, nova-volume is still configured in keystone. I copied the nova.conf and cinder.conf file onto paste bin - http://pastebin.com/xtpVKzs0.
