--- Comment #5 from Conrad Meyer <cem at freebsd.org> ---
The problem is that `name` in vtcon_ctrl_port_name_event (via `payload` in
vtcon_ctrl_process_event, via vtcon_ctrl_task_cb) has a leading space in it. 
(prep_devname rejects names with spaces, double quotes, and trailing slashes,
as well as . and .. components.)

virtio_console isn't prepared to create a device name for host
VIRTIO_CONSOLE_PORT_NAME strings that prep_devname will reject.  It would be
relatively easy to replace bad characters with underscores, or strip
leading/trailing spaces.
