charset="utf-8" From: Hannes Reinecke With commit 5ffbaeed16 ("hw/nvme: fix controller hot unplugging") namespaces get moved from the controller to the subsystem if one is specified. That keeps the namespaces alive after a controller hot-unplug, but after a controller hotplug we have to reconnect the namespaces from the subsystem to the controller.
