Seapath, the Configuration Project to Build a Platform/Cluster...
summary
SEAPATH is an LF_ENERGY open source configuration project that assembles existing pieces into an industrial VM cluster for substation real‑time controls, using KVM + PREEMPT_RT, Ceph, Corosync/Pacemaker, Open vSwitch, Ansible and GitHub Actions. It targets ~250 µs acquisition and 1–3 ms actuation latencies (claiming <100 µs precision in some specs), deploys from a Debian/Yocto ISO + USB then run Ansible playbooks, supports SR-IOV and PTP via host/PTP‑KVM, runs ~2,000 CI tests in lab and factory simulators, and moves to production soon.
