Virtual testbeds are essential tools for evaluation of cyber-security problems and cyber-security solutions in embedded control systems such as those that control the power grid. However, without explicit control, virtual testbed behavior is not repeatable, which limits our ability to replay a testbed experiment to re-create a surprising event, or even isolate and fix a bug. In this paper we consider extensions to TimeKeeper emulation framework aimed at improving its repeatability. One approach steps through assembly language instructions, the other asks emulated applications to report their own progress through virtual time. Empirical data demonstrates the potential of our proposals.
