QEMU 的挑战者

引用自 https://github.com/astro/microvm.nix :

Hypervisor Language Restrictions  
qemu C    
cloud-hypervisor Rust no 9p shares  
firecracker Rust no 9p/virtiofs shares  
crosvm Rust 9p shares broken 35w 行
kvmtool C no virtiofs shares, no control socket  
stratovirt Rust no 9p/virtiofs shares, no control socket  

还有的:

想不到在 kata 中内部还有一个: dragonball

不开源的

asure 自然就不用说了,必须是 hyper-v 了

挑战者联盟: rust-vmm

rust-vmm 的生态: Image

Cloud Hypervisor

https://github.com/cloud-hypervisor/cloud-hypervisor

这个项目的存在,意味着完全没有任何的必要看 kvmtool 的了。

主要的目录:

甚至还有 vhdx 的支持

stratovirt

我看基本上已经被放弃了,一年才几十个提交

ai 时代的 agent sanbox 挑战

2026-09-27 还没仔细看,为什么不去直接使用 firecracker 之类的东西啊

不过我很赞同这个想法, https://news.ycombinator.com/item?id=49879883#49880271

A new chip solves nothing. Nobody wants to hear this but there is no solution for the security risks posed by agents today. You can put it in a sandbox, it doesn’t make a difference, for it to be useful it inherently needs wide, unattended access. Put a human in the loop and you just end up bottlenecking it and throwing away any purported productivity gains. Auto mode doesn’t matter either, it’s trivial to trick and for the agent to break out.

sandbox 其实会影响效率,ai 基本上都可以自动的在 /tmp 上创建文件,分析测试,根本不需要 我们来控制。
