cocoonstack

macOS VM engine for x86 Linux/KVM, built on cocoon. Boots real macOS guests (Sequoia, Tahoe) via QEMU + OpenCore + OVMF, with ghcr golden images, snapshot & clone, per-VM SMBIOS identity, CNI networking (real LAN IP via TC redirect), reachable VNC, and a Docker-like CLI. For macOS CI runners, cloud Macs, and ephemeral dev environments.
