I have an Ubuntu 14.04 Vagrant box that I am trying to use on a Windows 10 host.
The box is not the issue as it works fine on other systems.
My Virtualbox version is currently 5.1.28, I tried the latest version which is when the problem started so I rolled back to 5.1.28 hoping that would fix it, to no avail.
My Vagrant version is 2.0.0.
This is what I get when I run vagrant up
λ vagrant up

The guest machine entered an invalid state while waiting for it
to boot. Valid states are 'starting, running'. The machine is in the
'unknown' state. Please verify everything is configured
properly and try again.
If the provider you're using has a GUI that comes with it,
it is often helpful to open that and watch the machine, since the
GUI often has more helpful error messages than Vagrant can retrieve.
For example, if you're using VirtualBox, run `vagrant up` while the
VirtualBox GUI is open.
The primary issue for this error is that the provider you're using
is not properly configured. This is very rarely a Vagrant issue.
I thought this might be a Firewall issue, so I disabled the Firewall, but am still seeing the same issue.
How can I get Virtualbox/Vagrant to work on Windows 10?
EDIT: The issue was that Windows Firewall had closed ports that were previously open on my system before I updated to the Fall Creators Update, specifically in this case port 22. I created an exception to allow that port 22 through, now it works as expected.
