Public bug reported:

When a different process say neutron sends an exception to nova that
Exception is not handled by nova and the error message is not relayed
correctly to the cli.

For example;  
I tried the following command failed due to a restriction:

"nova interface-attach vm --net <net-id>

Expected Result:
What was expected when this command failed was an error message as follows " VM with ports belonging to subnets across enter prises is not allowed in VSP"

Actual Result:
However, instead this message was relayed back to the cli "ERROR (ClientException): The server has either erred or is incapable of performing the requested operation. (HTTP 500) (Request-ID: req-fd69f004-591c-4ea8-b7b6-088a74cbe518)"
