Tsirkin <mst@xxxxxxxxxx> I dont know, if that is feasible for MSI, but the transport(virtio_pci) should already know the number of virtqueues, which should match the number of vectors, no? In fact, the transport has to have a way of getting the number of virtqeues because find_vq returns ENOENT on invalid index numbers.
