Open Stack

Hi,

I installed an Openstack Grizzly cluster based on Ubuntu 12.04, there are 1
control node, 1 database node, 1 quantum network node and 1 compute node, I
list all installed services at the control node and the database node.
Control node: nova-api, nova-scheduler, nova-consoleauth, nova-novncproxy,
nova-conductor, rabbitmq, quantum-server, keystone, horizon, glance
Database node: mysql

All of the nova services are running, however, nova-api is not running.
When I manually start nova-api service, I will get an error as below. Can
someone give me some advises?

Any help is appreciated.
