No, it's horribly insecure.
One option is to generate a temporary keypair and use ssh. Or you can
make the guest talk to an internal unix-domain socket, tunnel that
through virtio-serial, terminate virtio-serial in lkvm, and direct it
towards the local X socket. It's more work than exposing X11 via tcp,
but if the user said -nolisten tcp, you must respect it.
