This Error happens because openstack-nova-api and openstack-nova-metadata-api use the same ports. You can start nova-api stopping metadata-api service and starting nova-api before, then start again metadata-api service.

$ service openstack-nova-api start

$ service openstack-nova-metadata-api

This should fix your issue. After this you can set up boot order to this processes
1
update-rc.d openstack-nova-api defaults [order]
Copied!
Example:
If openstack-nova-metadata-api got an order boot of S90 openstack-nova-metadata-api, you should use update-rc to set nova-api start before nova-metadata-api
1
update-rc.d openstack-nova-api defaults 90
Copied!
This will set the priority of nova-api with the priority of nova-metadata-api, wich means that nova-api will run before metadata-api.
