How to install kali linux in virtual box

You can install VirtualBox on Kali Linux, allowing you to use virtual machines (VMs) inside of Kali Linux. However if you are wanting to install Kali Linux as a VM, you want our Kali Linux Guest VirtualBox guide.

VMs are great. There are many upsides with using them. One of the being, able to run multiple Operating Systems (OSs) at the same time. You can have your host machine “untouched”, and then only interact with the guest VMs. Another is when something is going right, take a snapshot. When something goes wrong, revert back.

VirtualBox is free and open source. There are a few other software such as QEMU, KVM/Xen with virt-manager. Then there is also VMware Workstation & Fusion, which is a commercial software (there is VMware Player which is free but it is limited in features).

Preparation

Before trying to install VirtualBox, please make sure your version of Kali Linux is up-to-date, and if required, reboot the machine:

[email protected]:~$ sudo apt update [. ] [email protected]:~$ [email protected]:~$ sudo apt full-upgrade -y [. ] [email protected]:~$ [email protected]:~$ [ -f /var/run/reboot-required ] && sudo reboot -f [email protected]:~$ 

Download

The first thing we are going to do is import VirtualBox’s repository key:

[email protected]:~$ curl -fsSL https://www.virtualbox.org/download/oracle_vbox_2016.asc|sudo gpg --dearmor -o /etc/apt/trusted.gpg.d/oracle_vbox_2016.gpg [. ] [email protected]:~$ curl -fsSL https://www.virtualbox.org/download/oracle_vbox.asc|sudo gpg --dearmor -o /etc/apt/trusted.gpg.d/oracle_vbox.gpg [. ] [email protected]:~$ 

We then move onto adding VirtualBox’s repository. We add this to a separate file, so it does not interfere with Kali Linux’s main repository. We also will be making sure to state where the keyring is at so the files can be properly signed. Our CPU architecture is amd64. You may need to alter the example below if yours is different.

One thing to bear in mind, Kali Linux is based on Debian, so we need to use Debian’s current stable version (even though Kali Linux is a rolling distribution). At the time of writing, its “bullseye”:

[email protected]:~$ echo "deb [arch=amd64] https://download.virtualbox.org/virtualbox/debian bullseye contrib" | sudo tee /etc/apt/sources.list.d/virtualbox.list [email protected]:~$ 

As we have altered our network repository, we need to re-build the cache:

[email protected]:~$ sudo apt update [. ] [email protected]:~$ 

As VirtualBox has various kernel modules (e.g. vboxdrv , vboxnetflt and vboxnetadp ), we need to make sure they are kept up-to-date when Kali Linux’s kernel gets updated. This can be achieved using dkms:

[email protected]:~$ sudo apt install -y dkms [. ] [email protected]:~$ 

Setup

Now its time to install VirtualBox itself (along with its Extension Pack to expand VirtualBox’s advanced features):

[email protected]:~$ sudo apt install -y virtualbox virtualbox-ext-pack [. ] [email protected]:~$ 

When prompted, read and accept the license.

You can now find VirtualBox in the menu or start it via the command line:

[email protected]:~$ virtualbox [email protected]:~$ 

If you now wish, you are able to install Kali Linux in a VirtualBox VM (on Kali Linux).

How to Install Kali Linux on VirtualBox

Kali Linux is a Debian-derived Linux distribution designed for penetration testing. With over 600 preinstalled penetration-testing programs, it earned a reputation as one of the best-operating systems used for security testing. As a security-testing platform, it is best to install Kali as a VM on VirtualBox.

Kali has a rolling release model, ensuring up-to-date tools on your system. Also, there is an active community of users providing ongoing support.

This step by step tutorial shows you how to install Kali Linux on VirtualBox.

• At least 20 GB of disk space
• At least 1 GB of RAM (preferably 2) for i386 and amd64 architectures
• VirtualBox (or alternative virtualization software)

Steps For Installing Kali Linux on VirtualBox

Since these instructions take you through the installation process in a virtual environment, you need to ensure you have one set up on your system. In this article, we are using VirtualBox, as it is a simple to use, open-source virtualization solution.

In case you do not have VirtualBox installed, use this step-by-step VirtualBox installation guide.

Step 1: Download Kali Linux ISO Image

On the official Kali Linux website downloads section, you can find Kali Linux .iso images. These images are uploaded every few months, providing the latest official releases.

Navigate to the Kali Linux Downloads page and find the packages available for download. Depending on the system you have, download the 64-Bit or 32-Bit version.

Step 2: Create Kali Linux VirtualBox Container

After downloading the .iso image, create a new virtual machine and import Kali as its OS.

1. Launch VirtualBox Manager and click the New icon.

2. Name and operating system. A pop-up window for creating a new VM appears. Specify a name and a destination folder. The Type and Version change automatically, based on the name you provide. Make sure the information matches the package you downloaded and click Next.

3. Memory size. Choose how much memory to allocate to the virtual machine and click Next. The default setting for Linux is 1024 MB. However, this varies depending on your individual needs.

4. Hard disk. The default option is to create a virtual hard disk for the new VM. Click Create to continue. Alternatively, you can use an existing virtual hard disk file or decide not to add one at all.

5. Hard disk file type. Stick to the default file type for the new virtual hard disk, VDI (VirtualBox Disk Image). Click Next to continue.

6. Storage on a physical hard disk. Decide between Dynamically allocated and Fixed size. The first choice allows the new hard disk to grow and fill up space dedicated to it. The second, fixed size, uses the maximum capacity from the start. Click Next.

7. File location and size. Specify the name and where you want to store the virtual hard disk. Choose the amount of file data the VM is allowed to store on the hard disk. We advise giving it at least 8 gigabytes. Click Create to finish.

Now you created a new VM. The VM appears on the list in the VirtualBox Manager.

Step 3: Configure Virtual Machine Settings

The next step is adjusting the default virtual machine settings.

1. Select a virtual machine and click the Settings icon. Make sure you marked the correct VM and that the right-hand side is displaying details for Kali Linux.

2. In the Kali Linux – Settings window, navigate to General > Advanced tab. Change the Shared Clipboard and Drag’n’Drop settings to Bidirectional. This feature allows you to copy and paste between the host and guest machine.

3. Go to System > Motherboard. Set the boot order to start from Optical, followed by Hard Disk. Uncheck Floppy as it is unnecessary.

4. Next, move to the Processor tab in the same window. Increase the number of processors to two (2) to enhance performance.

5. Finally, navigate to Storage settings. Add the downloaded Kali image to a storage device under Controller: IDE. Click the disk icon to search for the image. Once finished, close the Settings window.

6. Click the Start icon to begin installing Kali.

Step 4: Installing and Setting Up Kali Linux

After you booted the installation menu by clicking Start, a new VM VirtualBox window appears with the Kali welcome screen.

Select the Graphical install option and go through the following installation steps for setting up Kali Linux in VirtualBox.

1. Select a language. Choose the default language for the system (which will also be the language used during the installation process).

2. Select your location. Find and select your country from the list (or choose “other”).

3. Configure the keyboard. Decide which keymap to use. In most cases, the best option is to select American English.

4. Configure the network. First, enter a hostname for the system and click Continue.

5. Next, create a domain name (the part of your internet address after your hostname). Domain names usually end in .com, .net, .edu, etc. Make sure you use the same domain name on all your machines.

6. Set up users and passwords. Create a strong root password for the system administrator account.

7. Configure the clock. Select your time zone from the available options.

8. Partition disks. Select how you would like to partition the hard disk. Unless you have a good reason to do it manually, go for the Guided –use entire disk option.

9. Then, select which disk you want to use for partitioning. As you created a single virtual hard disk in Step 3: Adjust VM Settings, you do not have to worry about data loss. Select the only available option – SCSI3 (0,0,0) (sda) – 68.7 GB ATA VBOK HARDDISK (the details after the dash vary depending on your virtualization software).

10. Next, select the scheme for partitioning. If you are a new user, go for All files in one partition.

11. The wizard gives you an overview of the configured partitions. Continue by navigating to Finish partitioning and write changes to disk. Click Continue and confirm with Yes.

12. The wizard starts installing Kali. While the installation bar loads, additional configuration settings appear.

13. Configure the package manager. Select whether you want to use a network mirror and click Continue. Enter the HTTP proxy information if you are using one. Otherwise, leave the field blank and click Continue again.

14. Install the GRUB boot loader on a hard disk. Select Yes and Continue. Then, select a boot loader device to ensure the newly installed system is bootable.

15. Once you receive the message Installation is complete, click Continue to reboot your VM.

With this, you have successfully installed Kali Linux on VirtualBox. After rebooting, the Kali login screen appears. Type in a username (root) and password you entered in the previous steps.

Finally, the interface of Kali Linux appears on your screen.
