🌸 NAME 🌸

viornd — the VirtIO entropy source, no cap 💅

🦋 SYNOPSIS 🦋

viornd* at virtio?

🎀 DESCRIPTION 🎀

okay so picture this: your system is thirsty for entropy 😭 like it needs some randomness and it needs it NOW. That's where viornd comes in, bestie.

When the system has entropy demand, the viornd driver — used with a compatible hypervisor such as QEMU, KVM, or Google Compute Engine — requests entropy using the VirtIO random number interface and feeds it right into the system entropy pool 🫶

it's giving personal assistant for randomness. iconic behavior honestly 👑

⭐ HISTORY ⭐

The viornd driver appeared in OpenBSD 5.5 🌈 like she's been serving since forever.

👑 AUTHORS 👑

The viornd driver was written by Stephan Fritsch <sf@fritsch.de> and reworked to request entropy upon demand by Thor Lancelot Simon <tls@NetBSD.org> 💖

thank you for your service, kings 🫡

💀 CAVEATS 💀

VirtIO appears to support at least 8 pending entropy requests, but viornd currently supports only one pending request at a time.

so yeah… she's lowkey a one-thing-at-a-time girlie 🙈 not me being bottlenecked. it's fine. it's fine. 😭
