When the nova-api services starts from its own standalone binary it registers itself in the services table. The original wsgi script in nova/wsgi/nova-api.py did not, leading to the bug referenced below. The new wsgi script at nova.api.openstack.compute.wsgi, modelled on a similar thing used for the placement API, provides the necessary service registration. If a ServiceTooOld exception happens while trying to register the service then a very simple (currently very stubby) application is loaded instead of the compute api. This application returns a 500 and a message. Some caveats/todos: * wsgi apps managed under mod-wsgi (and presumably other containers) are not imported/compiled/run until the first request is made. In this case that means the service handling does not happen until that first request, somewhat defeating the purpose if the api is a bit idle.

To learn how to use Nova's API, consult the documentation
available online at:
https://developer.openstack.org/api-guide/compute/
https://developer.openstack.org/api-ref/compute/

Operators
---------
To learn how to deploy and configure OpenStack Nova, consult the
documentation available online at:
https://docs.openstack.org
For information about the different compute (hypervisor) drivers
supported by Nova, please read:
https://docs.openstack.org/developer/nova/feature_classification.html
In the unfortunate event that bugs are discovered, they should
be reported to the appropriate bug tracker. If you obtained
the software from a 3rd party operating system vendor, it is
often wise to use their own bug tracker for reporting problems.
In all other cases use the master OpenStack bug tracker,
