Title:
EC2 API RunInstances does not support idempotency
Status in OpenStack Compute (Nova):
Fix Released
Bug description:
The EC2 API RunInstances call supports the inclusion of a ClientToken.
The ClientToken consists of 64 ASCII characters or less. The first
RunInstances call with a given ClientToken launches an instance, but
future RunInstances calls with the same token have no effect. Client
tokens are valid for at least 24 hours.

http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/Run_Instance_Idempotency.html
I guess the way to tackle this is to add some persistent data into the
CloudController class, maybe just a dict of client tokens and
"earliest expiration times", and provide some method for periodically
purging them?
