Do you have all of the latest fixes for Ocata? You should be at version 
15.0.7 if you're on the latest Ocata fix release.

Is the instance properly mapped to a cell? Try querying the nova_api 
database:

select * from nova_api.instance_mappings where instance_uuid = 
"e564c631-896c-458c-93ab-b1c88f444fff";

Did the instance go to ACTIVE state or did it fail to schedule? If it 
failed to schedule, it would be in the nova_cell0 database and should be 
in ERROR state. You could query the cell0 database with:

select * from nova_cell0.instances where uuid = 
"e564c631-896c-458c-93ab-b1c88f444fff";

Otherwise see #3 in the Cells FAQs page here:
