BareMetal is an x86-64 exokernel written entirely in hand-coded Assembly. This repo adapts it to run natively inside Firecracker microVMs. No BIOS, no UEFI, no PCI bus - just virti…

A simple web server with some static content to server.

Can we get smaller VM hosts? I’ve seen some minimums at 512MB for a host. I need 8MB at most sometimes. Update: Fourplex (this host) uses a 1GB minimum.

Newlib has been ported: https://github.com/ReturnInfinity/BareMetal-newlib4

The plan is to get existing *nix programs ported over, yes. That will require some more work (ideally a compatibility layer/library).

Working on that now ;)

Correct. BareMetal (the kernel) doesn't have context switching or userland. Think of the kernel as just a hardware abstraction layer.

It’s always fun to see this get brought up on Hacker News! I’m the developer behind BareMetal OS. Keep in mind that this is all geared toward raw compute and throughput. No ring-3,…

Keyboard is supported. NVMe, AHCI, ATA, and VirtIO for storage. A few gigabit network adapters from Intel, Realtek, and also VirtIO. A 10gbit intel network driver is currently bein…

Interesting to see it written in higher-level languages!

Good point! I've added some text about wozmon to the README.

Yes - it uses the BareMetal OS kernel. I also wrote that.

That was the primary reason - a fun weekend project converting 6502 Assembly to x86-64 line by line. The x86-64 version comes in at a 384-byte binary due to instructions being a bi…

Agreed. Not sure what the status of the company is either. Their GitHub repos have been quiet for years.

Kano - https://kano.tech/us/original Looks like their website has changed around. They used to have a kit that came with a raspberry pi (that you had to assemble yourself) and thei…

Does this support writing to a linear frame buffer? Would be interesting to port to run on my OS if so.

TextNow/Hushed provides me with a local number to use. Any "burner" phone app should work as well for that.
