Hi, It seems that the Move instance creation to conductor commit [1] changed when and how the instance.delete notification is emitted for an unscheduled instance. Unfortunately the legacy notification doesn't have test coverage and the versioned notification coverage are still on review [2] for this case. Before [1] the instance.delete for an unscheduled instance is emitted from here [3]. But after [1] the execution of the same delete operation goes to a new direction [4] and never reaches [3]. Before [1] the new test coverage in [2] was passing but now after [1] is merged the test_create_server_error fails as the instance.delete notification is not emitted. Is it an intentional change or a bug? If it is a bug could you give me some pointers how to restore the original notification behavior?
