I installed a new fresh install of Ubuntu 14.04, and I compare with my
real platform.

In fact, it was olders entries of /etc/sudoers.d/nova-rootwrap  (maybe installed by an old Devstack setup). 
I've correct the file and it works fine ! 

For information, the good line in /etc/sudoers.d/nova-rootwrap : 
nova ALL=(root) NOPASSWD: /usr/local/bin/nova-rootwrap /etc/nova/rootwrap.conf *

** Changed in: nova
       Status: Incomplete => Invalid

Bug description:
  I started to install Openstack Juno yesterday,  I'm on Ubuntu 14.04.1 
  Keystone and Glance services are working,  now I have an error with the 'nova-api' service. 

  When I launch the service manually by 'nova-api' command, all is working. 
  But when I launch 'service nova-api start' , after some seconds, the service stopped with the following log error :

  I tried to add some arguments in '/etc/nova/nova.conf' 
  (like 'root_helper = sudo nova-rootwrap /etc/nova/rootwrap.conf'),  I checked the '/etc/sudoers.d/nova_sudoers',  but each time I get this error. 

  If I start the service manually just by 'nova-api' command, I'm able to retrieve the image list, for example.  
  Just the service should be misconfigured, but I don't know why, I followed the documentation (12-02-2015).
