Would it make sense to relax the current limitation in libvirt and allow <disk type='nvme'/> (which is meant for cases where the backend is a NVMe disk) to be on something else than 'virtio' bus?
This is really orthogonal to the emulated NVMe controller. A <disk type='nvme'> can theoretically back any disk frontend. I don't remember now why we actually mandate it only for virtio. Do you? Apart from that, it doesn't make that much sense to use <disk type='nvme' for an emulated NVMe drive again. You are way better of using direct PCI asignment.
