We built BareMetal OS - a minimal exokernel with sub-millisecond cold boot and hardware level microVM isolation. We think it's small (VMs can use as little as 4MiB of RAM) and fast enough to be genuinely interesting to build on. So we&

I’d be interested in attempting to run this in a network- enabled 32MiB RAM microVM.

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 virtio-net and virtio-block over MMIO. ~800µs cold start in Firec

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).

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, no multitasking (we do support multiple cores though), and

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 being developed. Send works on it currently.

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 bit longer.

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

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.
