Evolution of SPDK vhost Towards Secure Container Storage Service

on YouTube ↗24m

" summary

SPDK vhost is converted from busy polling to an interruptable vhost target that uses an epoll/eventfd abstraction so reactors and spdk threads block instead of pinning cores. Implementation uses a Linux AIO backend and exports devices via NBD to lightweight VM‑based secure containers, supports logical volumes and snapshots, and exposes rpc for management. Idle CPU drops to <1%, while benchmarks show interrupt mode can be under one‑third throughput of polling in a worst case, though AIO tests are only ~5–8% slower.
