  • Applications available in unikernels?
    2 projects | | 10 Jun 2022
    I'm with that organization that works on and . If you aren't a software engineer but still would like to use unikernels you're in luck - we also have a package repository at (running as a go unikernel on GCP) that will allow you to run and deploy pre-made applications. If you don't see something that you'd like to us there's also a way of importing docker containers into unikernels via ops which works for most (but not all) applications.
  • Ask HN: Software with biggest potential for positive impact in 5 years?

    I think Unikernels like NanoVMs ( will become more important. They are more efficient and more secure than than full operating systems. Right now, I think there are no good monitoring solutions available (or at least I am not aware of any). You can't just ssh to your server, so if something goes wrong, it can be hard to debug. And they are certainly not integrated into bigger monitoring solutions like Dynatrace. But once the infrastructure is available, I would expect a large percentage of Linux servers to be replaced with unikernels.

    For instance the filesystems have no permissions because there are no users because it is only running one process. Linux is ~30M LOC and half of that is drivers. When you deploy to a cloud you only really need a handful of drivers - something to talk to the disk, the network, a clock, etc. That's very different than deploying to bare metal servers where you have hundreds of different nics, usb, disk drives, etc. .... but it goes a lot further than that. The CFS scheduler and others are written specifically with the intention that the operating system is going to have to manage tens or hundreds of applications with tens of users. If you go to AWS and boot up a linux instance you'll find around a hundred programs running without you installing anything - even if it is on a vm with only one thread. Multiple processes which unikernels eschew come with a ton of baggage. Shared memory, IPC calls, scheduling, permissions, etc. We used to get questions asking why we didn't just make patches to linux (which this paper argues for btw) and the answer is simple - doing so is actually more work and harder to deal with than just writing a new unikernel specific kernel from scratch which is what we did. Might be worth pointing out that I've worked at a unikernel company for the past 5 years that is in charge of the open source and toolchains.

    You an also build from source here: && .

    There are also packages available through AUR/homebrew and the like: .

    The script is only there facilitate the 'install' such as ensuring you have qemu installed locally or assessing whether you have kvm/hvf rights/etc.

    Also, I don't think this is documented yet but you can target various PRs/builds with ops via this way:

    ops run /bin/ls --nanos-version d632de2

    This isn't true.

    Both and are Go unikernels running on Google Cloud. (I'm with NanoVMs that is the maintainer of these projects.)
