Vagrant box fails trying to log to a path the box was created from

This is a very specific error, and pretty obvious what's going on, I just don't know how to correct it. Don't see a specific answer on this.

There was an error while executing `VBoxManage`, a CLI used by Vagrant
for controlling VirtualBox. The command and stderr is shown below.

Command: ["startvm", "670fc20e-25e1-404f-b241-c8ae5d816a72", "--type", "headless"]

Stderr: VBoxManage: error: RawFile#0 failed to create the raw output file /Users/johnsmith/Desktop/Inflection Point Development/vbox1/ipd-developnode/inflectionpoint-saas.com/ubuntu-xenial-16.04-cloudimg-console.log (VERR_FILE_NOT_FOUND)
VBoxManage: error: Details: code NS_ERROR_FAILURE (0x80004005), component ConsoleWrap, interface IConsole

So this is on a different computer, and it exposed the fact obviously that log writing was going to somewhere else besides the box (/Users/johnsmith/Desktop/Inflection Point Development/vbox1/ipd-developnode/inflectionpoint-saas.com/ubuntu-xenial-16.04-cloudimg-console.log). Since I'm johnsmith on the creating computer and jsmith on the one I want to install the box, I can't even create that path - how do I change the original package's location to write that log file to inside the created box itself? Thanks!

OK, solution found!

If you are packaging a box to share, you have to change this setting BEFORE you package it. Open VirtualBox. Select the box in question (running or not). Then click on settings, and then change the path under serial port as follows:

./ubuntu-xenial-16.04-cloudimg-console.log

this will be created for users in the path that you have your Vagrantfile - which should always work.

PS I have no idea how I wound up with the convoluted path but I think it happens when you vagrant up from some directory besides the root folder for your vagrant settings..
