Add Content under Step 2 Vagrant Tutorial Troubleshooting Section

I run the Windows 8.1 and Above script to install all BeLL's Dependencies including VirtualBox and Vagrant.
I suspended my virtual machine using the command vagrant suspend. Then I issued the command vagrant up in order to restart my machine. However, I got an error message saying "Vagrant up: There was an error while executing VBoxManage, a CLI used by Vagrant". My OS is Windows 8.1.

Re installing other version of virtual box ( 5.1.x ) solves this problem. Don’t install 5.2 version of virtual box since it is not supported by vagrant installations.

I found the same error that someone was facing and its possible solutions at this link: hashicorp/vagrant#1809.
I fixed the error by killing the process "VBoxHeadless" in Task Manager (Windows 8.1), and the command vagrant up worked afterwards.

We can add the following content under Step 2 Vagrant Tutorial Troubleshooting Section as the 4th item:
4. When you run vagrant up from command prompt on windows after running vagrant suspend, you might get the following error: "Vagrant up: There was an error while executing VBoxManage, a CLI used by Vagrant". A possible solution is killing the process "VBoxHeadless" in Windows Task Manager, and the command vagrant up might work afterwards. For more information visit here

I would say a fix is in order for this problem, but i don't think the problem is best fix by adding a solution to when something goes wrong. Try to fix the original install process instead.
