Using the v1.1/{tenant_id}/servers/{server_id}/action API call, you can change the flavor/instance type of the running instance. 

Here's an example of resizing an instance via the nova command line tool (with debug on to see the API calls).

First, create the instance:


$ nova boot --image bc6e9a0c-7ede-4c54-9f22-401dd87ec367 --flavor 1 ken
