Hi , Using nova-manage service list to check the nova-network on the compute up or down. If down , please check the log file to ensure the compute can connect to the controller . Thank

@Indeep

Try to Check the logs in /var/log/nova/nova-api and network logs. Restart all openstack related services including message server rabbitmq/qpidd services and try to create the network.

I am still not done with this part. And i cannot proceed to Horizon installation till i am done with this as i will be missing steps. So is it feasible for my project to miss tseps at this point of time. Please provide me with more solutions.

Hi,

Try to look into nova-network service is started? if not, look for logs in /var/log/nova/nova-network.

Regards Sateesh

Try to restart the nova services and check the status. Also see if you have loaded the source file(rc file) or not.

Do you use nova-network or neutron as networking service? Did you reinstall or restart the services?

Check for the errors in log files of nova, in /var/log/nova and mention the errors here.

I can only find one negative line in all the log files.

==> /var/log/nova/nova-cert.log <== 2014-04-01 21:11:25.189 1037 WARNING nova.openstack.common.db.sqlalchemy.session [req-ed77e3d1-cbd3-49ea-8383-62ccc974babc None None] SQL connection failed. 10 attempts left.
