Sylve – A management plane for FreeBSD (ZFS, VMs, jails, clustering)
I’ve been working on Sylve, a management plane focused on making FreeBSD infrastructure easier to manage. It integrates closely with FreeBSD (Bhyve, ZFS, networking) and provides a UI + API for managing VMs, jails, and clusters across nodes. It features: * VM (Bhyve) and jail management * ZFS-based storage management (with Zelta for backups) * Multi-node clustering (based on Raft) * Runs in ~256MB RAM (even with clustering enabled) * Built-in web terminal (Ghostty/WASM) * Integrated networking (bridges, DHCP via dnsmasq) * Samba share management The backend is written in Go, and the…

hey guys. the other day i was migrating hosting providers and i just needed something not too heavy and convenient to spin up my backups for awhile and realised there is almost nothing out there. kimchi hasn't been updated for years and cockpit is heavy. so here's something i came up with in a couple hours because of a sudden urge, nothing fancy just basic creation with cloud init, lifecycle management and image/storage, but it's modern-ish and it compiles to a 8.4mb binary inclusive of the embedded web UI, CLI and API, and only dep is libvirt.

Hey HN! I just released go-nbd, a lightweight Go library for effortlessly creating NBD servers and clients. Its a neat tool for creating custom Linux block devices with arbitrary backends, such as a file, byte slice or what I'm planning to use it for, a tape drive. While there are a few partially abandoned projects like this out there already, this library tries to be as maintainable as possible by only implementing the most recent handshake revision and baseline functionality for both the client and the server, while still having enough support to be useful. I'd love to get your feedback :)
