I agree with Itamar. Dafna, there are several BZs which are related to snapshot calculations. I think it would be better if you have one BZ to concentrate all snapshot calculation issues you found, which we'll handle when we can (future for now). In this BZ we'll make sure to handle the error.

Version-Release number of selected component (if applicable): si13.3 How reproducible: 100% Steps to Reproduce: 1. create a quota of 30GB and a vm with 16GB disk 2. run vm as stateless (run-once) 3. Actual results: 1. we are calculating the full disk size and failing snapshot creation 2. text of error should be added Expected results: 1. fix calculation of stateless 2. fix error 3. stateless should not be calculated in quota since its temporary Additional info:
