[Sylvain Bauza (sylvain-bauza)]

The stack shows an issue with the ironicclient. That can possibly be a configuration problem, but either way it's not related to Nova.

[Sylvain Bauza (sylvain-bauza)]

As explained in IRC, that looks like a configuration problem :

- https://github.com/openstack/python-ironicclient/blob/master/ironicclient/client.py#L78 takes the endpoint value from ironic_url in parameters
- whose value is taken from a config opt https://github.com/openstack/nova/blob/master/nova/api/openstack/compute/baremetal_nodes.py#L60
- where https://github.com/openstack/nova/blob/master/nova/conf/ironic.py#L29-L31 is default to None (meaning you have to set it)

[zhaolihui (zhaolh)]

The Unexpected API Error was raised when ironic.admin_username, ironic.admin_password, ironic.admin_url and ironic.admin_tenant_name in the configure file was not setted.
It is a configuration problem.
