Ejercicio: Crear un box desde una maquina virtual

VBoxManage list vms
vagrant package –base «Nombre de la MV» –output maquina.box
no suele ser la forma habitual para generar .box
- son poco eficientes, muy grandes

mate@myKDE:~/.vagrant.d/Vagrant/Prueba1
$ VBoxManage  list vms
"Prueba1_default_1530475736924_80879" {7b97fa45-52aa-46a0-9b93-61c6921b1247}
mate@myKDE:~/.vagrant.d/Vagrant/Prueba1
$ vagrant package --base "Prueba1_default_1530475736924_80879" --output test.box
