I noticed that you implemented a high-performance VM fork. However, to me, it seems like a general-purpose KVM project. Is there a reason why you say it is specialized for running AI agents?

I keep so so so many opencode windows going. I wish I had bought a better SSD, because I have so much swap space to support it all. I keep thinking I need to see if CRIU (checkpoint restore in userspace) is going to work here. So I can put work down for longer time, be able to close & restore instances sort of on-demand. I don't really love the idea of using VMs more, but I super love this project. Heck yes forking our processes/VMs.

Cool approach. Are you guys planning on creating a managed version?
