`vagrant up` is hanging at the "waiting for machine to boot" stage

[collinmmccabe]

I'm a Vagrant noob here, so this might be an easy fix, but every time I try to use the master version of bga-workbench to create a VirtualBox VM via vagrant (on OS X, if that's helpful), it keeps getting hung up on the machine boot stage, and then exits out with the following error:

...
==> default: Waiting for machine to boot. This may take a few minutes...
    default: SSH address: 127.0.0.1:2222
    default: SSH username: vagrant
    default: SSH auth method: private key
Timed out while waiting for the machine to boot. This means that
Vagrant was unable to communicate with the guest machine within
the configured ("config.vm.boot_timeout" value) time period.

If you look above, you should be able to see the error(s) that
Vagrant had when attempting to connect to the machine. These errors
are usually good hints as to what may be wrong.

If you're using a custom box, make sure that networking is properly
working and you're able to connect to the machine. It is a common
problem that networking isn't setup properly in these boxes.
Verify that authentication configurations are also setup properly,
as well.

If the box appears to be booting properly, you may want to increase
the timeout ("config.vm.boot_timeout") value.

Any ideas what my problem might be and how to fix it? Thanks!

So, it appears that the problem was with the v.customize line in the Vagrantfile, which will break with xenial64 and many others in VirtualBox 6+. I changed that line to:
v.customize [ "modifyvm", :id, "--uartmode1", "file", File::NULL ]
and now everything appears to be running smoothly...

Thanks for the report @collinmmccabe . For some reason the setup still works on my machine, both with the original vagrant config and your adjustment above. Unfortunately I don't know enough about Vagrant to know what might be going on.

I've just committed some updates to the vagrant setup that I've used for more recent projects, maybe that will help.
