[salt-users] nova.get_configured_provider()' could not be found

Hi,

I installed salt from git, I also installed python-cloud and
python-novaclient in CentOS 6, I set openstack configuration files in
cloud.providers.d and cloud.profiles.d.

But running "salt-cloud --list-providers" got an error of
nova.get_configured_provider()' could not be found".

I looked at salt/cloud/__init__.py, the whole nova.* things are
missing in self.clouds which assigned by the
salt.loader.clouds(self.opts) in class Cloud __init__, and which
caused the error.

What I could be missing here? Appreciate any clues how to fix it.

Thank you.
