Nice work on Shuru — I remember looking at it when I was researching this space. You went with a Rust wrapper on Apple’s Virtualization framework right?

I have been working on something similar but on top of firecracker, called it bhatti (https://github.com/sahil-shubham/bhatti).

I believe anyone with a spare linux box should be able to carve it into isolated programmable machines, without having to worry about provisioning them or their lifecycle.

The documentation’s still early but I have been using it for orchestrating parallel work (with deploy previews), offloading browser automation for my agents etc. An auction bought heztner server is serving me quite well :)

bhatti's cli looks very ergonomic! great job!

also, yes, shuru was (still) a wrapper over the Virtualization.framework, but it now supports Linux too (wrapper over KVM lol)

Is there a way to store configuration/data of applications running on a Bhatti VM on the host, ala Docker volumes?

Yes! Checkout the bhatti volume

They are ext4 blocks which exist independent of sandboxes.

Wow, that’s quite nice! I see that’s at VM time, any plans to add the ability to add them after the fact? I am really enjoying bhatti!
