The xen_hvm_early_write() path better wouldn't be taken in this case; while port 0xE9 can be used, the hypercall path is quite a bit more efficient. Put that first, as it may also work for DomU-s (see also xen_raw_console_write()).While there also bail from the function when the first domU_write_console() failed - later ones aren't going to succeed.
