    Also related is Propolis from Oxide who worked on live migration with Bhyve https://github.com/oxidecomputer/propolis

    Anyone heard anything from dragonflyBSD lately? This sounds like something that might go well with HammerFS?

      I am using FreeBSD, not DragonflyBSD, but I happen to be on a DragonflyBSD developer mailing list, which is normally low traffic, except that I have noticed recently a lot of messages with various patches, mentioning both bug fixes and newly implemented features.

      So the project is alive and it seems more active than previously.

    Looks like this could really become a game changer for the FreeBSD folks using bhyve. The author often complained about this missing feature and he was also contributing to the Sylve project. Looks like he's crafting something.

    What’s FreeBSDs story like for Docker these days?

    I love FreeBSD. But I reluctantly had to migrate one of my home servers to Ubuntu Server because I needed Docker support as well as ZFS. Ubuntu Server, compared to FreeBSD, is a complete clusterfuck of an OS. And I regret the effort I spent migrating.

      There is also this which was not mentioned by other commenters.

      There's experimental support for Podman and OCI containers on FreeBSD 14.3 and later, with some additional system configuration required [0], [1]. I've been playing with it off and on with FreeBSD 15.0 and 15.1, but I'm not using it for anything I depend on.

        Nice. I’ll have a read of that later. Thank you

      I used to use Ubuntu a lot about 7 years ago. I saw the writing on the wall. Once they started forcing snap down people’s throats, especially. I’ve been on Debian ever since and have been very happy. I also have run many other OS’s and I feel that Debian is still a good blend of polished and still friendly to the hacker.

        Yeah Debian is nice. But at the time of switching, only Ubuntu offered ZFS precompiled in their official repos.

        I did, for a period, run some other distro with DKMS but that was a massive pain to keep up-to-date due to ZoL’s piss poor documentation and messy build tools.

        This was quite a few years ago though. Long before even FreeBSD synced with ZoL for OpenZFS. So the problems I encountered have likely matured tenfold since.

        But if I’m going to the hassle of installing a new OS then I might as well install FreeBSD again because I just prefer it to Linux (nothing against Linux in general, my laptops and PCs all run Arch)

      My current setup for Docker (Podman really in my case):

          Proxmox -> Linux VMs -> Podman containers inside Linux VMs
      
      My plan:

          FreeBSD's bhyve hypervisor -> Linux VMs -> Podman containers inside Linux VMs
      
      So basically just ditching Proxmox for FreeBSD/bhyve. Then at long last I'll be, again, systemd-free.

        I did consider the bhyve approach myself, before I made the switch. But it was still pretty experimental at the time (iirc) and wanted something reliable otherwise I’d have a wife and two kids moaning at me that their stuff isn’t working haha!

        But maybe you’re right that it’s worth reconsidering now.

    Nice! Can we have high availability / clustering for jails next?

    so bhyve getting live migration finally means sylve might actually be usable for production clusters, been waiting on this.
