Hi Manuel,

You may wish to check out the Blazar project or get in touch with their 
contributor team:

https://wiki.openstack.org/wiki/Blazar

Blazar adds a reservable dimension to Nova's compute service and there 
is a notion of something that "cleans up" VMs after their reservation is 
expired. It may fit your needs here.

Best,
