  • VZ.framework is very limited, Hypervisor.framework is the better analogue to KVM

  • I saw this blog post title and wanted to read it, as I thought this is something we really wanted when I worked back at Encore - and lo and behold what website I ended up on!

    Great work lads, seeing those old shell scripts brought back memories, but this is awesome to see you've solved the problem now to make your own lives easier!

    Any plans to open source crackling? I was looking into cross platform microVM's after reading about sbx recently.

  • I think Encore is great and do really cool things, but this post is AI;DR from the first sentence.

  • By experience, getting Firecracker to run well on M-series macs is quite the undertaking. I'm not at all surprised Encore decided to take this path considering their customer base!

    At Lovable we decided to spend ~1 engineering month getting our sandbox infrastructure to be 100% runnable on Mac and on Linux with predictable builds using Bazel etc.

    But we actively decided to take a different route than Encore and run nested virtualization, which on macOS means vfkit -> QEMU -> Kind + Firecracker vm(s). It's been invaluable to get the same development and testing tools on both platforms tbh.

  • I wonder how necessary/useful this is, in light of the amazing smolvm microvms from https://smolmachines.com.

    (Not snark, not affiliated, just happy and impressed with smolvm and genuinely curious.)

  • > most engineers at Encore develop on a Mac

    They are solving the wrong problem.

  • A suggestion to the author -- don't outsource your writing to AI, or, if you do, go over it with a fine-tooth comb and remove every trace of Claudisms from it.

    I read the subtitle: "What it takes to boot the same microVMs on Apple's hypervisor, and the one capability Apple will not let you have." and immediately navigated away.
