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?

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? root@bodega:~# ps aux | grep nova nova 914 0.0 0.0 37952 1312 ?
