I did pip install oslo.messaging and the system told me that's already installed. And yes i verified that all packages listed are installed.

See if you missed the package for oslo messaging. Verify that you installed all of the packages listed in the guide.

i did the upgrade of oslo.messaging and it solves the probleme and that's weared because i did the upgrade and the update of all my packages before that.

#sudo pip install --upgrade oslo.messaging

Good deal. When you see errors in tracebacks about importing from "*" it's usually because the code doesn't include it:

Traceback (most recent call last): File "/usr/bin/cinder-manage", line 62, in <module> from oslo import messaging ImportError: cannot import name messaging

I've seen this as well in Trusty with Icehouse python-oslo.messaging and, here's the weird part, it works on some puppet hosts and not on others (all of which were installed with puppet ie, the same way.)
