I must have the same VM in other computers but I don\'t want to download the whole box, php mysql, etc...

You just have to download the VM box only one time and make the all changes and configurations that you need and then re-package this one on a new box called "myVM.box".
Then you comment in the Vagrantfile the following line
#config.vm.box_url = "https://site_of_boxes..."
and used
config.vm.box = "myVM"
It starts up without download any VM.
