Vagrant Error: Unable to Mount VirtualBox Shared Folders (Guest Additions, vboxsf)

Question

The Issue

I installed Vagrant on Windows 10 so I can create a personal local development environment in a virtual machine. Everything I've read about Vagrant said I can even spin up multiple systems and test communication between them with NAT port forwarding. But first, I just want to get one development environment virtual machine created before I go too far with the rest of it.

I installed VirtualBox, Vagrant, PuTTy, and PuTTYGen, per this SitePoint tutorial: https://www.sitepoint.com/getting-started-vagrant-windows/. Next I created a vagrant project folder on C: drive, did vagrant init, deleted the Vagrantfile, and finally, vagrant init ubuntu/trusty64. Then I did vagrant up, but the process failed with the error:

Vagrant was unable to mount VirtualBox shared folders. This is usually because the filesystem "vboxsf" is not available. This filesystem is made available via the VirtualBox Guest Additions and kernel module. Please verify that these guest additions are properly installed in the guest. This is not a bug in Vagrant and is usually caused by a faulty Vagrant box. For context, the command attempted was:

mount -t vboxsf -o uid=1000,gid=1000 vagrant /vagrant

The error output from the command was:

: No such file or directory

Here's a screenshot of my Windows command line:

And here's a text version:

Vagrant was unable to mount VirtualBox shared folders. This is usually
because the filesystem "vboxsf" is not available. This filesystem is
made available via the VirtualBox Guest Additions and kernel module.
Please verify that these guest additions are properly installed in the
guest. This is not a bug in Vagrant and is usually caused by a faulty
Vagrant box. For context, the command attempted was:

mount -t vboxsf -o uid=1000,gid=1000 vagrant /vagrant

The error output from the command was:

What I tried already

This post seemed the most promising in my research.

Unfortunately, none of the solutions offered, nor any of the links provided solved the issue. I've tried a bunch of stuff already, but I'm not a system admin (which, I'm guessing is the skillset that you'd need to troubleshoot this). It was particularly troubling that many of the "solutions" from 2013/2014, are more recently indicated as not working any more. These solutions talk about something to do with symlinks not working, installing plugins like vagrant-vbguest, and something about vbox additions not matching something. I don't really understand all of that, but I tried my best. Here is what I tried already that hasn't solved it yet:

1. vagrant plugin install vagrant-vbguest. Vagrant shows the plugin as installed, but I get the same error on vagrant up.

2. List of links I read in researching this issue that provided no working solution.

   • https://www.virtualbox.org/ticket/12879 (This VirtualBox ticket is referenced by posters in some of the other listed links. Unfortuantely, this ticket doesn't fix the issue. It's not fixed and is still broken ... OR ... perhaps this ticket is related, but slightly differerent than the issue I and others are still experiencing).

My Questions

1. I suspect the issue is with VirtualBox, not Vagrant. Is this true?

2. How can I fix this so I can continue with the tutorial?

3. There seems to have been a drastic drop in Vagrant questions answered on Stack Overflow since around 2014. What is the reason for this? Is Vagrant/VirtualBox no longer considered "best practice"? Is there a better solution so users are ignoring the Vagrant questions?

Again, I'm not a system administrator, but I am technically savvy and can follow technical directions.

Answer 1

vagrant plugin install vagrant-vbguest

This didn't work for me, it seems to be incompatible with vagrant 1.9.2, I uninstalled the latest version of virtual box (5.1.16) and installed version 5.1.12 with the latest version of vagrant 1.9.2 and homestead and it works for me.

Answer 2

You can downgrade VirtualBox or edit the line in the file:

On my setup this was Line 206 of:

C:\HashiCorp\Vagrant\embedded\gems\gems\vagrant-1.9.2\lib\vagrant\util\platform.rb

on my host machine.

I did this and it worked fine on Windows 10! I would like to add what I did with line 206:

Before edit: "\\?\" + path.gsub("/", "\")

After edit: path.gsub("/", "\")

Answer 3

Guest Additions is incompatible with the version of VirtualBox. Autoupdating VirtualBox Guest Additions will solve probably related issue:

vagrant plugin install vagrant-vbguest

I exprerienced this issue with these stack:

• Windows 10
• Oracle VirtualBox 5.1.16
• Vagrant 1.9.2
• config.vm.box = "hashicorp/precise64"
