Ah, this is a problem between ruby and some operating systems. Some OS are case sensitive for ruby requires and others aren't. Unfortunately, I seem to have packaged the v0.3 packages with an OpenNebula folder containing uppercase letters. This is probably the cause of your problem. Please rename the folder lib/OpenNebula to lib/opennebula and tell me if this solved your problem.

Thanks. Indeed, starting passenger in the OGF OCCI folder solves that problem but another one comes up:

      You can stop Phusion Passenger Standalone by pressing Ctrl-C.

it looks like you successfully installed passenger. You should issue the

passenger command within the OGF OCCI folder. If you just start passenger,

it does not know, which files to serve and thus the error.

Please follow these steps (from the OGF OCCI Wiki):

3.) Download ogf-occi-0.3_beta2.tar.bz2 or ogf-occi-0.3_beta2.zip from


4.) Untar / unzip the file

5.) Change to the folder ogf-occi

6.) Change the configuration in etc/occi-server.conf

7.) Run the OCCI server with

passenger start
