OSv Unikernel ([email protected])

OSv 0.57.0 has been recently released - github.com/cloudius-syste…. New build mode to hide the non-glibc symbols and libstdc++, ZFS code extracted out of the kernel in form of a dynamically linked library libsolaris.so, ...

Finally, #OSv can run on AWS Graviton!

Are Unikernels Ready for Serverless on the Edge? This academic paper compares OSv and Nanos against Firecracker Linux microVMs, Docker containers, and secure gVisor containers - arxiv.org/html/2403.0051…. The folks at @geneziodev may find it insightful!

We have just added an alpha version of ext4 filesystem support! It is based on lwext4 library which originates from HelenOS. For details please look at #readme" target="_blank" rel="nofollow noopener">github.com/cloudius-syste…

The recording of @razvandeax 's talk at FOSDEM'24 (together with corresponding resources - slides, demos) is available online[1]. Check it out to discover why and how "Unikernels are Here" 🚀 [1] fosdem.org/2024/schedule/…

Very interesting use case of using #OSv_unikernel to build fast and very resource-efficient server-less platform - fosdem.org/2024/schedule/…

The recording of my #FOSDEM24 talk about the most recent OSv enhancements has been just released - video.fosdem.org/2024/ud2208/fo…! Tune in to learn about how we use Xconfig to build a custom kernel of 788K in size that runs an app with only 1.2MB of memory.

If you happen to be at #FOSDEM in Brussels this coming weekend and are interested in recent improvements to @OSv_unikernel , please come to watch this presentation fosdem.org/2024/schedule/…

Finally after 6 years we have PR to implement AWS ENA driver and now OSv can run on new Nitro instances. Feel free to help us review it - github.com/cloudius-syste…

Interesting presentation by @geneziodev about how they use @OSv_unikernel to build their server-less platform - youtube.com/watch?v=xRmRXC…

OSv can now run statically linked executables as well as dynamic ones via Linux' ld-linux-x86-64.so.2 instead of OSv's built-in dynamic linker. Stay tuned when this is going to officially land on master!

We are a very small team of volunteers so beyond pure maintenance there is not much we can work on in terms of new features and improvements. Therefore we would like to seek your feedback on what we should focus on next - github.com/cloudius-syste…

@penberg @DorLaor @lightpriest @nukemberg @glcst @ScyllaDB We have an example of deno (nodejs in Rust) working on OSv. At least some older version of it worked on OSv. As long as it is not a statically linked executable it should work. May need larger TLS which you can increase. See github.com/cloudius-syste…

@OSv_unikernel @DorLaor @lightpriest @nukemberg @glcst @ScyllaDB I have not! I know the Unikraft folks did bunch of work to unlock Rust so I kind of expect sqld to not run out-of-the-box. Would be kind of cool to give it a go though.

I think unikernels are making a comeback and is going to be important for serverless infrastructure. 🧵👇 1/

@DorLaor @lightpriest @nukemberg @penberg @glcst @ScyllaDB @penberg out of curiosity, have you tried to run libsqlhq on OSv?

@lightpriest @nukemberg @penberg @glcst @OSv_unikernel @ScyllaDB It was a pleasure to work together. Some of my lines of code pushed to OSv (actually not but it's a nice statement)

The video recording of my talk about @OSv_unikernel at #FOSDEM2023 has been just released - fosdem.org/2023/schedule/…. Enjoy!

If you happen to be at #FOSDEM2023, please come and listen to Waldek Kozaczuk's (@waldiko) presentation about most recent OSv enhancements - fosdem.org/2023/schedule/…

Finally, one can check an interesting use case of SeaweedFS (distributed storage system) running on OSv - #readme" target="_blank" rel="nofollow noopener">github.com/cloudius-syste… @SeaweedFS
