Ejecutar aplicaciones X11 desde invitado vm-bhyve en host.
La(s) aplicacion(es) se ejecutan en la máquina virtual invitada, sin embargo, se muestra en el host. La importancia de esto radica en que puede ejecutar una aplicación en una lugar y mostrar la ventana en el host.
Si una aplicación no es soportada en la máquina host pero bien soportada en la vm podrá ejecutarse en una ventana del host.
Ejecutar Firefox en una vm y mostrarlo en el host FreeBSD 13.0
basado en el reenvío X11 usando ssh.
