With this, you have a virtio-serial connection between the host and
the guest.  The unix socket exists between a client program and the
qemu invocation on the host, with the qemu end being wired to the host
end of the virtio-serial connection.

You cannot have a unix socket between a host and a guest, they run
different kernels.
