Step 1: Install VirtualBox

If you don’t already have VirtualBox installed, you can install it with the following commands:

  1. Update package list and install dependencies:bashCopy codesudo apt update sudo apt install virtualbox virtualbox-ext-pack Optionally, you can install virtualbox-guest-additions for better integration of the guest OS in the virtual machine (e.g., shared clipboard, better display support).
  2. Verify installation:bashCopy codevirtualbox --help

Step 2: Launch VirtualBox and Create a New VM

  1. Open VirtualBox: Open VirtualBox either by searching for “VirtualBox” in the application launcher or by running:bashCopy codevirtualbox
  2. Create a New VM: In VirtualBox, click on New to start the process of creating a new VM.
  3. Choose OS and Name:
    • Choose a name for your VM.
    • Select the operating system (OS) type you want to install (e.g., Linux, Windows).
    • Select the version of the OS you’re going to use (e.g., Ubuntu, Windows 10).
  4. Set Memory (RAM): Allocate the desired amount of RAM to your VM. It’s recommended to allocate at least 2GB for a basic Linux installation and more for more intensive operating systems.
  5. Create a Virtual Hard Disk:
    • Select Create a virtual hard disk now.
    • Choose the disk type (e.g., VDI or VHD).
    • Choose Dynamically allocated if you want the disk size to grow as data is written to it, or Fixed size for a predefined disk size.
    • Set the size of the virtual hard disk (e.g., 20GB for a minimal installation).

Step 3: Configure the VM

  1. Modify Settings for Multiple VMs: You can create multiple VMs by repeating the above process. Each time, choose a new name and configuration, ensuring that each VM has its own virtual disk and allocated resources (e.g., different RAM size, disk space, etc.).
  2. Configure Network (Optional):
    • Go to Settings > Network and adjust the network adapter. By default, VirtualBox uses NAT, which allows the VM to access the internet. If you need a bridge network or other configurations, you can adjust it here.

Step 4: Install an Operating System in the VM

  1. Start the VM: Once the VM is created, select it and click Start.
  2. Select the installation media:
    • Insert the installation ISO (e.g., Ubuntu ISO file) by selecting File > Virtual Media Manager and adding the ISO file or by selecting the ISO directly when the VM starts.
    • Follow the OS installation steps as you would on a physical machine.

Step 5: Create More VMs

Repeat the process for additional virtual machines:

  • New > Name > OS type > Memory > Virtual Hard Disk for each new VM.
  • You can configure each VM with different OS types or versions (e.g., one with Ubuntu, one with Windows).

Step 6: Automate VM Creation (Optional, for advanced users)

If you want to create multiple VMs automatically (e.g., using scripts), you can use VBoxManage, the command-line tool for VirtualBox. Here’s how to create a VM using a script:

  1. Open a terminal and use the VBoxManage command to create a new VM:bashCopy codeVBoxManage createvm --name "VM1" --ostype "Ubuntu_64" --register VBoxManage modifyvm "VM1" --memory 2048 --cpus 2 --vram 128 --nic1 nat VBoxManage createhd --filename "/path/to/VM1.vdi" --size 20480 VBoxManage storagectl "VM1" --name "SATA Controller" --add sata --controller IntelAHCI VBoxManage storageattach "VM1" --storagectl "SATA Controller" --port 0 --device 0 --type hdd --medium "/path/to/VM1.vdi" VBoxManage storageattach "VM1" --storagectl "SATA Controller" --port 1 --device 0 --type dvddrive --medium "/path/to/ubuntu.iso" VBoxManage startvm "VM1" Replace "VM1" with your VM name, adjust the --filename for the virtual disk location, and point to the correct .iso file for OS installation.You can repeat this for other VMs (e.g., "VM2", "VM3", etc.) in a script to automate the creation of multiple machines.

Step 7: Managing Multiple VMs

You can run multiple VMs at the same time by selecting and starting them individually, or you can manage them using VBoxManage:

  1. List all VMs:bashCopy codeVBoxManage list vms
  2. Start a VM:bashCopy codeVBoxManage startvm "VM1" --type headless
  3. Stop a VM:bashCopy codeVBoxManage controlvm "VM1" poweroff
  4. Show VM information:bashCopy codeVBoxManage showvminfo "VM1"

Additional Tips:

  • If you’re running many VMs, ensure your host system has sufficient resources (RAM, CPU, disk space).
  • You can adjust the number of CPUs and memory allocated to each VM based on your system’s capacity.
  • For automation and scripting, consider creating virtual machines via Vagrant, which integrates with VirtualBox and provides an easy way to manage multiple VMs.

By following these steps, you can easily create and manage multiple virtual machines on Ubuntu using VirtualBox.

Sure! Let’s break down the help output for the virtualbox --help command into clear bullet points, explaining it in simple terms, just like we’re chatting:

General Command Syntax:

  • virtualbox [options]
    You run this command to interact with VirtualBox from the terminal.

Key Options & Commands:

  • --help
    Shows the help information (this is what we’re discussing now).
  • --version
    Displays the version of VirtualBox installed.
  • --startvm <name|uuid>
    Starts a virtual machine by its name or UUID (unique identifier). You just specify the machine name and it boots up.
  • --controlvm <name|uuid> <command>
    Used to send commands to a running VM, like pausing, saving, or stopping it. You follow this with the VM’s name or UUID and the command you want to run (e.g., poweroff or pause).
  • --snapshot <name|uuid>
    Manage snapshots of a virtual machine. Snapshots are like save points, allowing you to revert to a previous state of the VM.
  • --list
    Displays a list of your VMs, settings, snapshots, etc. This is helpful to see what VMs you have set up.
  • --createvm
    Command for creating a new virtual machine. You specify settings (name, OS type, etc.) after this.
  • --register
    Registers an existing VM configuration with VirtualBox. Useful when you want to add a previously created VM that’s not yet registered.
  • --unregister
    Removes a VM configuration. This doesn’t delete the VM’s files but unregisters it from VirtualBox.
  • --modifyvm <name|uuid>
    Allows you to modify settings for an existing VM (e.g., changing RAM size or adding a network adapter).
  • --startvm <name|uuid> --type <headless|gui|separate>
    This starts a virtual machine in different modes:
    • headless mode: No graphical interface (runs in the background).
    • gui mode: Normal mode with the graphical interface.
    • separate mode: Like gui, but runs in its own window.
  • --stopvm <name|uuid>
    Shuts down a running VM.
  • --pausevm <name|uuid>
    Pauses a running virtual machine. It’s like putting it on hold.
  • --savevm <name|uuid>
    Saves the state of a VM. It’s similar to hibernating your computer; the VM state is saved, and you can restore it later.
  • --controlvm <name|uuid> resume
    Resumes a paused VM.
  • --snapshot <name|uuid> restore
    Restores a snapshot of the VM. Think of it as going back to an earlier save point.
  • --showvminfo <name|uuid>
    Displays detailed information about a VM, like its settings, status, and resources used.
  • --discardstate
    Discards the saved state of a VM (if it was saved earlier).

Options for VM Settings:

  • --memory <size>
    Sets the amount of RAM the VM can use.
  • --cpus <number>
    Determines how many CPUs or cores the VM can access.
  • --vram <size>
    Allocates video memory to the VM (useful for GUI-heavy OSes).
  • --nic<1|2|3|4> <type>
    Configures network adapters. You can set up how your VM connects to the internet or other machines (e.g., nat, bridged, or hostonly).
  • --audio <type>
    Sets up the audio for the VM. You can specify the type (e.g., alsa, pulse, etc.).
  • --usb
    Enables USB support for the VM. You can connect USB devices to the VM.
  • --usbdevice <device>
    Specifies a USB device to attach to the VM.

Storage & Virtual Disks:

  • --createhd <path>
    Create a new virtual hard disk for a VM.
  • --storagectl <name>
    Adds a storage controller (e.g., SATA, IDE) to the VM.
  • --storageattach <name|uuid> --storagectl <controller> --port <port> --device <device>
    Attach a virtual hard disk, CD/DVD drive, or other storage media to the VM.

Other Useful Options:

  • --showvminfo <name|uuid>
    Get detailed info about a specific virtual machine, like its CPU, RAM, and storage settings.
  • --help-all
    Displays all available options, including detailed descriptions of each one.

Example:

If you wanted to start a VM called “UbuntuVM” in headless mode:

bashCopy codevirtualbox --startvm "UbuntuVM" --type headless

Summary of Key Actions:

  • Create VM: --createvm
  • Start VM: --startvm
  • Modify VM: --modifyvm
  • Pause/Resume VM: --pausevm, --controlvm resume
