StratoVirt, a virtualization project implemented in the Rust language, provides both lightweight and standard virtual machine modes. For lightweight scenarios, StratoVirt achieves only the minimum set of devices required to run the business load, greatly reducing the types of devices that are redundant by traditional virtualization, significantly reducing overhead. Because in lightweight virtual machine mode, the memory base noise of a single virtual machine is less than 4MB, the startup time is less than 50ms, and the device’s extreme scalability supports millisecond latency.
