[Openstack] Cannot start "nova-api" service

By default both cinder and nova-api are listening on the same port 8776
(this should be a bug I think), you can try to change the default value in
the cinder.conf like: osapi_volume_listen_port = 8777 if you are running
the cinder and nova-api on the same machine.

11/13/2012 09:32 "nova-api" service
AM
Hello,
Can someone please help me with a nova-api issue. After install all the
nova services, all seem to be running fine, except for nova-api. I even
reboot my controller node, no luck. After reboot all services are running,
except nova-api. When I manually start nova-api, nova-api crashes with the
following error "error: [Errno 98] Address already in use". I installed
nova-volume earlier during the install process, but later on installed
cinder, and made the necessary modifications (as far as I can tell) to
nova-api.conf to use cinder for block storage. Should I uninstall
nova-volume?

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.
