Open Stack

Hi,

you should check your config settings again, especially the "auth_url"  
settings in the section(s) "[keystone_authtoken]" of all the config  
files.
Are all the services up (nova, cinder and neutron) and running? What  
is the output of 'nova service-list'?
Have you checked other log files for errors? Is there something  
interesting in nova-compute.log?

Regards,
Eugen
