Hmm, looks like you are using an old version of python-novaclient.  You might try grabbing from source.  The packages from launchpad are not supported in any way.  We try to provide relatively current packages, but we don't really have the resources to maintain and support them at this point.

What I'm doing is follow the Devstack Script but trying to install the components separately (one host with nova-network, other with nova-api, dashboard, and so on).

I was getting some problems with my (2) installation when trying to run the nova command (for example, to see my nodes, as we got with euca-describe-availability-zones verbose some time ago. Not working. So, I tried to run the same tool on the Devstack instalation and it didn't work too.
