This is working as designed. The guest might be gone from the hypervisor while the instance is shutdown, but nova continues to track quota against that instance, otherwise you potentially can't start the instance later if someone in the same project took the quota you were using in the meantime while your instance was stopped.

I thought that it is not reasonable. This leads to a waste of physical resources.
