[osv-dev] Booting Bare Metal

I am looking to boot the kernel I generated from the build script. How would one recommend doing so using grub? I have noticed that OSv doesn't support multiboot, or so it seems to me. I am not a grub expert by any means so that's why I am asking for some help. I am doing a school research

[osv-dev] Unikernels as highly isolated processes and an idea to implement limited fork/execve in OSv

Sometimes it might be more useful to think of unikernels as highly isolated processes instead of microVMs with a specialised guest OS. See Nabla processes - https://acmsocc.github.io/2018/slides/socc18-slides-williams.pdf . So given that I wonder if it would make sense/be feasible/applicable to

[osv-dev] Running Linux apps compiled and linked against musl

I think there are many apps these days built to run on Alpine Linux that uses musl instead of glibc. Given that OSv uses musl and extends it to expose as a subset of glibc, how difficult would it be to expose musl as-is at the same time and thus support musl-built Linux binaries? Is it even

Re: [osv-dev] OSv boots in 3ms on QEMU microvm machine

First please note that this and other old (5ms) firecracker boot times were recorded when running on my old 2013 MacBook Pro with 4-way 2.3GHz i7 cpu with Ubuntu 19.04 on it. I think it still a decent laptop and the cpus have not gotten that much faster (Moore's law is dead now, right?), but it

[osv-dev] Re: Capstan Build Fail and Fix

I am not golang expert either. Maybe others, original authors of capstan on the list can chime in. I will look into myself. If there is a lot of work we might just explicitly stick with v1. Either way, it would be good to express the explict dependency on the specific version rather than always

[osv-dev] Re: [COMMIT osv-apps master] webassembly: add 3 WASM examples - lua, sqlite and nginx - to run on wasmer

I do not know exactly how wasmer works, but I think on the first run of a given wasm file it transforms it into machine code and then stores in the cache for the faster start next time. With ZFS images the 2nd time will be faster as well. With ROFS the cache is on RAMFS so it transforms the

You can read it here - http://cs.iit.edu/~khale/docs/diver-ross19.pdf. It mentions OSv and capstan. The authors lay out ambitious plans to create specialized OSes build and deployment ecosystem - driver. Regarding capstan, one of the features it is missing is the ability to build images out
