✨ SYNOPSIS ✨

vmmci* at virtio?

🎀 DESCRIPTION 🎀

bestie, the vmmci driver gives virtual machines a whole control interface while they’re running inside OpenBSD vmm(4) hosts — and yes, vmm(4) is the virtual machine monitor 👑.

It handles shutdown and reboot requests coming from the vmm(4) host by signalling init(8): shutdown uses SIGUSR2, and reboot uses SIGINT. Respectively. Periodt. 💖
