In general, project branches referenced in devstack/master are either
release branches or slightly-lagging mirrors of trunk.

There was a recent change in python-novaclient where it now expects
tenantName, rather than tenantId, for NOVA_PROJECT_ID.  If you are using the
devstack sample data, you now need to set NOVA_PROJECT_ID to either 'admin'
or 'demo' (Before it expected '1' or '2').

I know that there has been work put into ec2 + keystone, but I have not
worked with it personally just yet.  Perhaps someone else has an update?

For server.create there is actually support in the underlying python library
for a key_name parameter (
https://github.com/rackspace/python-novaclient/blob/master/novaclient/v1_1/servers.py#L327),
but this has not yet been exposed through the CLI.  There is still work that
need to be done to catch the CLI up to the capabilities of the underlying
python library (keypairs, floating ips, security groups, volumes?)

Jesse summarized the flow for dashboard here, which  is related:

The main difference with novaclient vs. dash is that with novaclient the
tenant is specified, so the part where you use an unscoped token to grab a
tenant list is not needed.

Hope that helps!
