I'm using an emulated NVMe controller in QEMU (4.1.0) and want to see whether it's possible to use multiple namespaces in the same controller, each backed by a separate file. However this doesn't seem to be possible? This is how I use one controller and one namespace:
-drive file=nvme.img,if=none,id=D22
-device nvme,drive=D22,serial=1234
