Hi All; I have installed keystone, glance and nova compute services on controller node as instructed in OpenStack Installation Guide for Ubuntu 12.04/14.04 (LTS). I have to still configure the compute node separately. When I restart the services as directed on page 45 of the manual, nova-api is not starting. Further when I use the command "*nova image-list*". It returns "*ERROR (ConnectionError): ('Connection aborted.', error(111, 'Connection refused'))*. Here are some outputs, which may help to diagnose the issue:
------------------------ root@controller:/home/arauf# *service nova-api restart* *stop: Unknown instance:* nova-api start/running, process 13206 ------------------------------------------------------ root@controller:/home/arauf# *ps -eaf | grep "nova-api"* root 13521 1684 0 15:20 pts/1 00:00:00 grep --color=auto nova-api ------------------------------------------------------ root@controller:/home/arauf# *nova-manage service list* Binary Host Zone Status State Updated_At nova-cert controller internal enabled :-) 2014-10-09 12:18:57 nova-consoleauth controller internal enabled :-) 2014-10-09 12:19:01 nova-scheduler controller internal enabled :-) 2014-10-09 12:19:00 nova-conductor controller internal enabled :-) 2014-10-09 12:18:58 *NOTE: NOVA-API is not enabled* -------------------------------------------------------- *tail -30 /var/log/nova/nova-api.log* 014-10-10 14:10:49.573 20500 TRACE nova File "/usr/lib/python2.7/dist-packages/nova/openstack/common/processutils.py", line 193, in execute 2014-10-10 14:10:49.573 20500 TRACE nova cmd=' '.join(cmd)) 2014-10-10 14:10:49.573 20500 TRACE nova ProcessExecutionError: Unexpected error while running command. 2014-10-10 14:10:49.573 20500 TRACE nova Command: sudo nova-rootwrap /etc/nova/rootwrap.conf iptables-save -c 2014-10-10 14:10:49.573 20500 TRACE nova Exit code: 1 2014-10-10 14:10:49.573 20500 TRACE nova Stdout: '' 2014-10-10 14:10:49.573 20500 TRACE nova Stderr: 'Traceback (most recent call last):\n File "/usr/bin/nova-rootwrap", line 6, in <module>\n from oslo.rootwrap.cmd import main\nImportError: No module named rootwrap.cmd\n' 2014-10-10 14:10:49.573 20500 TRACE nova 2014-10-10 14:10:49.692 20507 INFO nova.openstack.common.service [-] Parent process has died unexpectedly, exiting 2014-10-10 14:10:49.692 20509 INFO nova.openstack.common.service [-] Parent process has died unexpectedly, exiting 2014-10-10 14:10:49.692 20507 INFO nova.wsgi [-] Stopping WSGI server. 2014-10-10 14:10:49.693 20507 INFO nova.wsgi [-] WSGI server has stopped. 2014-10-10 14:10:49.693 20508 INFO nova.openstack.common.service [-] Parent process has died unexpectedly, exiting 2014-10-10 14:10:49.692 20506 INFO nova.openstack.common.service [-] Parent process has died unexpectedly, exiting 2014-10-10 14:10:49.693 20506 INFO nova.wsgi [-] Stopping WSGI server. 2014-10-10 14:10:49.694 20508 INFO nova.wsgi [-] Stopping WSGI server. 2014-10-10 14:10:49.694 20509 INFO nova.wsgi [-] Stopping WSGI server. 2014-10-10 14:10:49.695 20506 INFO nova.wsgi [-] WSGI server has stopped. 2014-10-10 14:10:49.696 20508 INFO nova.wsgi [-] WSGI server has stopped. 2014-10-10 14:10:49.696 20509 INFO nova.wsgi [-] WSGI server has stopped. ------------------------------------- I am looking forward for a positive response.
