vagrant package how to save changes to new box - virtual-machine

Question

My question is related to this here but I do not get it to work.
I use a pre-made vagrant box from vagrantbox.es ( http://goo.gl/KwQSa2 ) and I want to make some changes and repackage the new virtual machine into a new vagrant box file.
To get the initial box, I add config.vm.box_url = "http://goo.gl/KwQSa2" to my vagrant file.
After invoking vagrant up I do vagrant ssh and then some operation (e.g. touch testfile.txt).
After logging out I use vagrant package which creates package.box.
Then I do vagrant destroy, add the path to package.box to config.vm.box_url in my vagrant file and do vagrant up again.
When I log into the VM, my testfile.txt is not there, so it looks like I packaged the unchanged box.
I tried other things such as vagrant box repackage without success.
What am I missing here?

Answer 1

When you package, you have to specify the UUID of the new VM created (by vagrant up) based on the base box.
NOTE: If you are using VirtualBox, it'll create a new VM with name - base_box_name-default-UUID.
When running
vagrant package --base name --output /path/to/name.box
The --base NAME, name should be either the new VM's name or its UUID.
You can get it by using the following command:
$ VBoxManage list vms
