Vish,

I am running cinder-api.   The following two lines are present in nova.conf.

volume_api_class=nova.volume.cinder.API
enabled_apis=ec2,osapi_compute,metadata

Do I need to re-sync the db, or add any additional lines to nova.conf?

No that is it. Are you sure a) you don't have another nova-api or nova-metadata or nova-api-os-compute process running? and b) that your nova.conf is being read properly?

Vish

As far as I can tell, no other nova-api, nova-metadata, nova-api-os-compute is running.   If there another way to confirm besides running "ps aux".  And how can I tell if nova.conf is being read properly?

Can you help me understand the following error message in the file:

2012-11-08 23:31:27 CRITICAL nova [-] [Errno 98] Address already in use

By address, are we talking about tcp port number? If so, what is the port number?

Thank you,
Ahmed.
