Kernel entropy is reseeded via RNDADDENTROPY but userspace PRNGs (numpy, OpenSSL) need explicit reseeding per fork. See [Firecracker's guidance](https:\u002F\u002Fgithub.com\u002Ffirecracker-microvm\u002Ffirecracker\u002Fblob\u002Fmain\u002Fdocs\u002Fsnapshotting\u002Frandom-for-clones.md).\n- Single vCPU per fork. Multi-vCPU is architecturally possible but not implemented.\n- No networking inside forks. Sandboxes communicate via serial I\u002FO only.\n- Template updates require a full re-snapshot (~15s). No incremental patching.\n\n## License\n\n[Apache-2.0](LICENSE)\n","Zeroboot 是一个通过写时复制分叉技术为AI代理提供亚毫秒级虚拟机沙箱的项目。其核心功能包括使用Rust语言编写，基于KVM和Firecracker技术实现极低延迟（p50约0.79毫秒）的虚拟机创建与执行环境，并且每个沙箱都是具有硬件强制内存隔离的真实KVM虚拟机。该项目特别适合需要快速启动和执行代码片段的场景，如在线编程评测、云函数服务等。同时，Zeroboot提供了Python和TypeScript SDK方便开发者集成到自己的应用中。目前处于工作原型阶段，支持自托管部署或通过官方提供的API进行访问。","2026-06-11 03:50:20","high_star"]
