You can now run same OCI images as containers or Firecracker microVMs

Is the OP the author of this? Because they are writing responses here that are unquestionably unedited LLM generated responses. The project looks cool, and I'm particularly glad to see a reach for a p2p container registry, but that sort of behavior doesn't lend credibility to something as critical as image infrastructure.

I hate how I feel about this: the sole contributor's account is not 2 month old, and yet they have created an org for this project, with all the bells and whistles in the README.

To me, a project that young, with a unique developer at the helm, cannot look "that nice", so I can't resist seeing it as too nice to be true, and being actually a scam or whatever.

I know that, thanks to AI, a solo dev can not only orchestrate an actual projects in a few days, but can ALSO take time to make a good looking README.

When, in the past, the focus was first on the code, then on the README.

It looks like OP only has an account here to self-promote, which also puts them in the same credibility tier as an advertiser.

There's actually two additional sockpuppet accounts (liquid64 / yakimbo90) in here self-promoting. Whole thing is throwing off a ton of red flags.

Sweet. I had hoped for someone to make a p2p container registry eventually. There is too much centralization with the current popular registries.

Where does the microvm kernel/initrd come from? How can it be built?

I just want a system that's as easy as "docker run ubuntu" but launches as a microvm instead, without me having to source a kernel or remember hugenormously long qemu incantation lines.

I think `smolvm` may fit the bill? I've been using it to run pi.dev in a sandbox.

I tried smolvm, and built several single binaries with it for different distros. Less than a month later, those same binaries now silently exit with code 0 and I have absolutely no idea what's wrong or how to diagnose.

We will be soon including this in Tarit, a firecracker alternative https://github.com/instavm/tarit

Currently we have to supply a kernel to run the OCI as a microVM with a warm pool.

  TARIT_KERNEL=/path/vmlinux

  taritd image build --oci ubuntu:24.04 --name ubuntu
  taritd vm create --image ubuntu

The kernel/initrd come from a regular OCI container image — there's no separate VM image format. Any OCI image containing /boot/vmlinux (and optionally /boot/initramfs.cpio.gz) works as a kernel image.

I don't think I've ever seen a kernel or initrd in a container image. The whole point of containers is not to duplicate the kernel, and you definitely don't need an initial ram disk since you already have a running operating system.

And if they don't have a kernel? You just specify kernel + initrd?

you don't have to source one manually — pullrun kernel install fetches a kata containers kernel into ~/.pullrun/kernels/vmlinux-<version>. One-time setup, then the daemon auto-discovers it.

If you run an ubuntu image with a kata kernel, do you have difficulty installing some packages? For example if you need linux-headers-$(uname -r) or linux-modules-extra-$(uname -r), it won't exist in canonical apt repos?
