Had the same problem, found that in /var/log/nova/nova-api.log the error message:

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'

Solution: Reinstalled oslo with the command: pip install --upgrade oslo.rootwrap

Problem resolved by changing the permission on a glance library file.

Re-installed the database and keystone being careful to follow the documentation when run commands as root and when to run commands as a regular user.

Do not do the database commands as root because this will cause permission problems later now that are difficult to resolve.

Thank you to those who tired to help - hope this post helps someone else.

Here is my hosts file: Controller name found but not the port 9292

cat /etc/hosts

#127.0.0.1 localhost #127.0.1.1 raid03 128.6.57.128 xxid03.xxx.xxx.xxx
10.255.255.255 broadcasthost 255.255.255.255 broadcasthost #

OpenStack Configuration

OpenStack

10.0.0.11 controller

OpenStack

10.0.0.31 compute1

Command I was trying to run was: glance image-list

Just to show the name "controller" can be found: # netstat | grep controller tcp 0 0 controller:mysql controller:35830 ESTABLISHED tcp 0 0 controller:35830 controller:mysql

The command worked a few days ago - not sure what changed but here are more details:

glance image-list

Error finding address for http://controller:9292/v1/images/detail?sort_key=name&sort_dir=asc&limit=20 (http://controller:9292/v1/images/deta...) : HTTPConnectionPool(host='controller', port=9292): Max retries exceeded with url: /v1/

In doing an initial install of OpenStack, with Ubuntu 14.07 and get the error described. Thank you for your help !
