virtualboxin the terminal - Checking the version with
vboxmanage --version
Method 2: Installing VirtualBox via Command Line (APT)
This method gives you more control and is preferred by many Linux users. It’s also faster than the GUI method.
Adding Oracle VirtualBox Repository
First, let’s add Oracle’s official repository to ensure you get the latest version:
wget -q https://www.virtualbox.org/download/oracle_vbox_2016.asc -O- | sudo apt-key add -Then add the repository:
echo "deb [arch=amd64] https://download.virtualbox.org/virtualbox/debian $(lsb_release -cs) contrib" | sudo tee /etc/apt/sources.list.d/virtualbox.listUpdate your package list:
sudo apt updateInstalling VirtualBox Package
Now install VirtualBox with:
sudo apt install virtualbox-7.0The installation process will automatically handle dependencies and kernel module compilation. You might see some warnings during installation – don’t worry, these are usually normal.
Method 3: Installing VirtualBox from Oracle’s Official Website
Sometimes you might want the absolute latest version or prefer manual installation. Here’s how to do it:
Downloading the .deb Package
- Visit the official VirtualBox website at virtualbox.org
- Navigate to the Downloads section
- Select “Linux distributions”
- Choose the Ubuntu version matching your system
- Download the .deb file (usually around 100-120MB)
Installing via dpkg
Once downloaded, navigate to your Downloads folder and run:
sudo dpkg -i virtualbox-7.0_7.0.X-XXXXX~Ubuntu~jammy_amd64.debReplace the filename with your actual downloaded file. If you encounter dependency issues, fix them with:
sudo apt-get install -fPost-Installation Configuration
Adding User to vboxusers Group
This step is crucial for proper VirtualBox functionality. Add your user to the vboxusers group:
sudo usermod -aG vboxusers $USERLog out and log back in for the changes to take effect. You can verify group membership with:
groups $USERInstalling VirtualBox Extension Pack
The Extension Pack provides additional features like USB 3.0 support, RDP, and disk encryption. Download it from Oracle’s website and install it either through the VirtualBox GUI (File > Preferences > Extensions) or via command line:
sudo vboxmanage extpack install Oracle_VM_VirtualBox_Extension_Pack-7.0.X.vbox-extpackTroubleshooting Common Installation Issues
Kernel Module Issues
If you encounter kernel module problems, try:
sudo /sbin/vboxconfigThis rebuilds the kernel modules. If it fails, you might need to install kernel headers:
sudo apt install linux-headers-$(uname -r)Permission Problems
If VirtualBox complains about permissions:
- Ensure you’re in the vboxusers group (as shown above)
- Check if virtualization is enabled in your BIOS
- Verify VT-x/AMD-V is available:
egrep -c '(vmx|svm)' /proc/cpuinfo
Creating Your First Virtual Machine
Basic VM Setup
Now for the fun part – creating your first virtual machine:
- Launch VirtualBox: Click on the VirtualBox icon in your applications menu
- Create new VM: Click “New” in the toolbar

- Create virtual hard disk: Choose VDI format, dynamically allocated, minimum 25GB
Installing Guest Additions
Guest Additions improve VM performance and provide better integration. After installing your guest OS:
- Start your VM
- In the VM window, click “Devices” > “Insert Guest Additions CD image”
- Install the additions inside your guest OS
- Restart the VM
This enables features like seamless mouse integration, shared clipboard, and better screen resolution.
Best Practices for VirtualBox on Ubuntu
Here are some tips to get the most out of your VirtualBox installation:
Resource allocation: Don’t allocate more than 50% of your host RAM to VMs
Snapshot management: Take snapshots before major changes – they’re lifesavers
Security updates: Keep both VirtualBox and guest OSes updated
Backup strategy: Regular backups of important VMs save headaches later
Performance Optimization Tips
To ensure smooth VM operation:
- Enable hardware acceleration: Make sure VT-x/AMD-V is enabled in BIOS
- Increase video memory: Allocate at least 128MB video memory for better graphics
- Use SSD storage: VMs perform significantly better on SSDs
- Adjust processor cores: Assign 2-4 cores depending on your host system
Studies show that properly configured VMs can run at 85-95% of native performance, making virtualization incredibly efficient for most use cases.
Security Considerations
When running virtual machines, keep these security aspects in mind:
- Network isolation: Use NAT or host-only networking for sensitive VMs
- Regular updates: Keep guest operating systems patched
- Antivirus protection: Install antivirus software in Windows VMs
- Encrypted VMs: Consider encrypting sensitive virtual machines
FAQs
Q1: Can I run VirtualBox alongside other virtualization software like VMware?
