Dear All,

I've successfully installed OpenStack for CentOS 6.3 (Folsom) and now I was trying
to add the OCCI support since we want to implement some APIs for testing the interoperability
with other cloud solutions.

I was following the instructions reported in this link: https://github.com/tmetsch/occi-os and
suggested by Florian Feldhaus. Unfortunately the distribution i was looking for (occi-os-folsom)
seems not be available in the repo.

$ pip-python install occi-os-folsom
Downloading/unpacking occi-os-folsom
Could not find any downloads that satisfy the requirement occi-os-folsom
No distributions at all found for occi-os-folsom
Storing complete log in /root/.pip/pip.log

From repo the only available distribution is the previous one ..

$ pip-python install openstackocci
Downloading/unpacking openstackocci
Downloading openstackocci-essex-1.1.tar.gz
Running setup.py egg_info for package openstackocci
Requirement already satisfied (use --upgrade to upgrade): distribute in /usr/lib/python2.6/site-packages (from openstackocci)
Installing collected packages: openstackocci
Running setup.py install for openstackocci
Successfully installed openstackocci
Cleaning up...

The problem is that with this previous one nova-api fails to start. See below the nova's api log file:

$ cat /var/log/nova/api.log

Many thanks in advance,
