technically yes.
it depend on if you cinder driver supports nvme over rdma as well.
ceph obviously does not as it use RBD to export the block storage.
the mounting of the NVMEoF devicve is handled by os-brick so form a
nova/qemu point of view its a host mounted block device. as such there
is no difference between that and iscsi because qemu is not directly
connecting to the storage backend.
