I know nova is not listening on 8774 for the nova image-list command. Thus, the log verifies that. If I installed all nova components, why is there no /usr/bin/nova-rootwrap ? /var/log/nova/nova-api.log

Still not solved but here is an update:

The module is on controller but failing in the nova-api.log .

Help would be appreciated. This is on icehouse.

Are you saying file /usr/bin/nova-rootwrap does not exist? The logs you post appear to indicate it does exist, but it is failing to import a module. Can you please double check.

According to the logs, you are missing python-olso.rootwrap. Maybe the packages have some broken dependancies. You can install this with apt-get install python-oslo.rootwrap. I just worry that for whatever reason it wasn't installed, you will run into more issues because of it later.

Yes sir, that is correct, /usr/bin/nova-rootwrap does exist. I will apt-get install python-oslo.rootwrap and post the results back.

This is what I get, I am not sure where python-oslo.rootwrap is supposed to reside but if not in /usr/bin it is not on the system yet the package information says it is supposed to be there.

Looks like the *.deb version on http://packates.ubuntu.com (trusty) installs (via dpkg -i) the component is in the same place as preciously in stalled with the package install.

[Errno 111] Connection refused is a different issue. Can you post your nova conf and the appropriate logs after running those commands?
