Container-based network emulation provides an accurate, flexible, and cost-effective application design and evaluation testing environment. Enabling virtual time to processes running inside containers essentially improves the temporal fidelity of emulation experiments. However, the lack of precise time management during operations, such as disk I/O, network I/O, and GPU computation, often leads to virtual time advancement errors observed in existing virtual time systems. This paper proposes VT-IO, a lightweight virtual time system that integrates precise I/O time for container-based network emulation. We model and analyze the temporal error during I/O operations and develop a barrier-based time compensation mechanism in the Linux kernel. VT-IO enables accurate virtual time advancement with precise I/O time measurement and compensation. The experimental results show that the temporal error can be reduced from 87.31% to 3.6% and VT-IO only introduces around 2% overhead of the total execution time. Finally, we demonstrate VT-IO’s usability and temporal fidelity improvement with a case study of a Bitcoin mining application.
