Re: [Openstack] [Nova] Unable to start nova-api
Trinath, You probably have a wrong config setting. Please check the value of 'network_api_class' in your nova.conf and confirm that the module with the specified class exists. The default value of this parameter is nova.network.api.API, so you should expect class 'API' in nova/network/api.py of your Nova codebase. Regards, Unmesh.
