failed neutron configuration - unit: nova-vmware/0: machine: 1 agent-state: error details: hook failed: cloud-compute-relation-changed

[Larry Michel]

With removal of neutron config from nova-cloud-controller, this charm is broken:

So charm should be getting the plugin information from neutron-api

[Larry Michel (lmic)]

I tested replacing the nova-cloud-controller relation with neutron-api relation in the charm, and I was able to deploy without any error. So, I'll link the branch I tested with to this bug.

[James Page (james-page)]

The nova-cc charm should still be propagating the network-manager and neutron plugin directly to the nova-compute-vmware charm, in the same way that they do for the stock nova-compute charm; so I think that switching the relation to the neutron-api does not make a huge amount of sense.
