Erros

gistfile1.txt

1) Failed to untar the box file. This is usually because you're attempting to add a box that isn't a valid box file. Please double check that the box file is properly packaged.



2) There was a problem with the configuration of Vagrant. The error message(s)
are printed below:

vm:
* Base MAC address for eth0/NAT must be set. Contact box maintainer for more information.

um possível motivo: https://groups.google.com/forum/#!topic/vagrant-up/suj0wWFVECc


- Acho que o 1º erro dpois gerou o 2º.
Copiar ~/.vagrant.d/boxes/sigvia do trab pra máquina de casa
ou
baixar http://sigvia-devel.s3.amazonaws.com/support/sigvia.box
e tentar vagrant box add $BOXNAME /path/to/downloaded.box, ou seja, vagrant box add sigvia /path/to/sigvia.box


vagrant box remove sigvia virtualbox (mas tive que remover depois tb pela gui do virtualbox)
