nova image-list gives error during installation

Hi

I am trying to install openstack in two nodes. I am following the manual http://docs.openstack.org/icehouse/in... . When I run the command "nova image-list" to verify nova configuration from page http://docs.openstack.org/icehouse/in... I got the error "ERROR (AttributeError): 'NoneType' object has no attribute 'replace'". I checked "glance image-list"and it was working. To resolve this error I uninstalled python-novaclient and then reinstalled it and then upgrade it using

  • pip uninstall python-novaclient
  • pip install python-novaclient
  • pip install --upgrade python-novaclient

After that I restarted all nova services and then run "nova image-list", then I got the error " ERROR (ConnectionRefused): Unable to establish connection to http://controller:8774/v2/3653a437d79..."

Now I have no idea what to do next to resolve to issue. Can anybody suggest me where I have gone wrong and how to resolve this issue?

Thanks

HI Yashpal, I have nova-api, nova-cert, nova-conductor, nova-consoleauth, nova-manage and nova-scheduler log files in the /var/log/nova folder. I have checked all these log files after running "nova image-list", but no log is generated for this command

I have ran into another problem. I restarted the system and then I ran command "source admin-openrc.sh" and then I ran "glance image-list", I got error "Invalid OpenStack Identity credentials." I have pasted log in http://paste.openstack.org/show/185962/ . "nova image-list" still gives previous error

Hey Anil, it would be helpful if you can post glance conf, nova conf and log files of glance and nova. From your below answer, I think few of your services are not running.

I have pasted nova.conf http://paste.openstack.org/show/190906/ glance-api.conf http://paste.openstack.org/show/190908/ and glance-registry.conf http://paste.openstack.org/show/190907/ . Logs are only generated in the glance api.log which is exactly same as the one pasted in my previous comment

Please make sure all of your nova related components are up and running. 

nova service-list

netstat -ntlp | grep 8774 (If its centos 6.X)

ss -ntlp | grep 8774 (If its centos 7)

"nova service-list" is giving error " Unable to establish connection to http://controller:8774/v2/3653a437d79..." and "netstat -ntlp | grep 8774" is returning no optput. I am installing openstack in Ubuntu 14.04.

Thanks

which means, nova services are not running in your controller node. make sure the following

service nova-scheduler status service nova-api status.

Post your /etc/nova/nova.conf from your controller node
