[one-users] OpenNebula OCCI 1.1

[florian.feldhaus at tu-dortmund.de]

Hi Amine,

there have been a few issues with OCCI 1.1 for OpenNebula v0.2. We fixed a
lot of them and plan to release a new version (0.3) in the next week. If
you can wait, I would very much recommend you to try out the next version
as soon as it is released. If you're interested, I would be glad to
provide a "beta" version to you for testing.

A few comments to your problem inline:

I haven't tested OCCI 1.1 for OpenNebula with OpenNebula Express, but
there should be no reason why this does not work.

The config files look OK.

This is strange. Maybe there are leftovers from the old OCCI server
included in the OpenNebula distribution. If you correctly installed OCCI
1.1 for OpenNebula, it should have moved away the old OCCI Server. Could
you please check (e.g. use diff or check the content of the files with
less) if the files from the ogf-occi-0.2.zip file have been installed to:
/usr/bin (e.g. occi-server)
/etc/one (e.g. occi-one.conf and occi-server.conf)
/usr/lib/one/ruby/cloud/occi (all the library files like StateMachine.rb,
CategoryRegistry.rb, ...)

Is the log output from /var/log/one/occi-server.log ?

This will probably not work. occi-compute is a script from the old OCCI
implementation and it is based on OCCI 1.1 which has a considerably
different interface specification.
