Vagrant Fails SSH on Linux Host, Works on Windows Host

To ensure that your Vagrantfile works correctly on two machines, Windows 7 with VirtualBox 6.1.50 and Linux Mint 22 with VirtualBox 7.1.4, follow these steps:

Preparing the Vagrantfile

1. Start by creating a new directory for your project and navigate into it.

mkdir my-project
cd my-project

2. Initialize a new Vagrant project by running the following command:

vagrant init

3. This will generate a Vagrantfile in the project directory. Open it in your favorite text editor.

Configuring the Vagrantfile

4. Define the two machines in the Vagrantfile. Here's an example configuration for each machine:

Vagrant.configure("2") do |config|

  # Windows 7 VirtualBox 6.1.50
  config.vm.define "windows7" do |windows7|
    windows7.vm.box = "windows7/amd64"
    windows7.vm.box_version = "2012"
    windows7.vm.provider "virtualbox" do |vb|
      vb.version = "6.1.50"
    end
  end

  # Linux Mint 22 VirtualBox 7.1.4
  config.vm.define "linuxmint22" do |linuxmint22|
    linuxmint22.vm.box = "ubuntu/bionic64"
    linuxmint22.vm.box_version = "20210818.0.0"
    linuxmint22.vm.provider "virtualbox" do |vb|
      vb.version = "7.1.4"
    end
  end
end

Replace the box names and versions with the ones appropriate for your operating systems.

5. To provision the machines, you can use shell scripts, Ansible, Puppet, or any other configuration management tool. For this example, we'll use a simple shell script.

6. Create a provision directory in the project root, and inside it, create two shell scripts, one for each machine:

mkdir provision
touch provision/install_windows.sh
touch provision/install_linux.sh

7. Write the scripts to install necessary software on each machine. For example, the install_windows.sh script might look like this:

#!/bin/bash
powershell -Command "Install-WindowsFeature -Name Web-Server"

8. In the Vagrantfile, configure the provisioning for each machine:

config.vm.provision "shell", inline: false, path: "provision/install_windows.sh"
config.vm.provision "shell", inline: false, path: "provision/install_linux.sh"

9. Save the Vagrantfile and close the text editor.

Running the Vagrantfile

10. To bring up the VMs, run the following command:

vagrant up

11. After the VMs are created, you can SSH into them using the following commands:

vagrant ssh windows7
vagrant ssh linuxmint22

Cleaning Up

12. When you're done with the VMs, you can destroy them using the following command:

vagrant destroy

This example demonstrates how to create and configure a Vagrantfile to work on two different machines with different operating systems and VirtualBox versions.
