The nvme-control interface allows snaps to manage and access NVMe controllers and namespaces via in-kernel NVMe interfaces (PCI & NVMe-oF). Provides access to enumerate devices, create/delete/attach/detach namespaces, and read device health/ telemetry data. Access is limited to NVMe management operations through sysfs, nvme-fabrics char device, and controller/namespace device nodes. Raw block I/O remains constrained by device cgroups. The nvme and nvme-tcp kernel modules may auto-load as needed.

See Interface management and Supported interfaces for further details on how interfaces are used.
