How to create a Kali Linux VM

Warnings

  • The installation scripts and provided tools may have bugs, be vulnerable to Man in the Middle (MitM) attacks or other vulnerabilities.

  • Adding additional repositories or tools for installing software extends your trust to those tool providers.

  • Please keep in mind that using such a VM or VM's based on the template for security and privacy critical tasks is not recommended.

  • Kali Linux distribution is a rolling distribution based constantly on Debian testing release, so it always will have newer software base than available in Qubes OS debian template. Keep in mind that it may result in problems (especially in regard to package dependency) not covered by this tutorial.

How to Create a Kali Linux VM

This guide is being created to give guidance on ways in which you could create a Kali Linux penetration testing VM (qube) in Qubes OS.

Kali Linux is the most widely used penetration testing Linux distribution.

There are multiple ways to create a Kali Linux VM:

  1. Create a HVM and use the official ISO to install the system or convert a Virtual Image. Explained here.
  2. Clone the Qubes OS latest Debian template image and turn it into a Kali Linux distribution:

Kali Linux HVM

  1. Download the Kali installation DVD

  2. Create a new HVM

  3. Start the HVM with attached CD/DVD

$ qvm-start <hvm-name> --cdrom <vm-name>:/home/user/Downloads/<iso-name>.iso

Kali Linux TemplateVM from a Debian template

This section will explain how to create your own Kali Linux TemplateVM based on a current stable Debian TemplateVM. The basic idea is to personalize the template with all the tools needed, and then spin up isolated AppVMs based on the template.

The steps can be summarised as:

  1. Install Qubes stable Debian template
  2. Upgrade the template to Debian testing release
  3. Add the Kali repository
  4. Update the template

Get Kali Linux GPG key

CAUTION: Before proceeding, please carefully read On Digital Signatures and Key Verification. This website cannot guarantee that any PGP key you download from the Internet is authentic. Always obtain a trusted key fingerprint via other channels, and always check any key you download against your trusted copy of the fingerprint.

This step is required since by (security) default a TemplateVM do not have a direct Internet connectivity. Users understanding the risks of enabling such access can change this configuration in firewall settings for the TemplateVM.

  1. Retrive the Kali Linux GPG key using a DispVM.
$ gpg --keyserver hkp://keys.gnupg.net --recv-key 44C6513A8E4FB3D30875F758ED444FF07D8D0BF6
$ gpg --list-keys --with-fingerprint 44C6513A8E4FB3D30875F758ED444FF07D8D0BF6 
$ gpg --export --armor 44C6513A8E4FB3D30875F758ED444FF07D8D0BF6 > kali-key.asc

  1. DO NOT TURN OFF the DispVM, the kali-key.asc file will be copied to the Kali Linux template in a further step.

  2. Make sure the key is the authentic Kali key. See the Kali website for further advice and instructions on verification.

Create a Kali Linux (rolling) template

These instructions will show you how to upgrade a Debian TemplateVM to Kali Linux.

  1. (Optional) Check for latest Debian stable template and install it (if not already done)
$ sudo qubes-dom0-update --action="search all" qubes-template-debian
$ sudo qubes-dom0-update <latest Debian template>
  1. Start your latest Debian template
$ qvm-start debian-<X>
$ qvm-run -a debian-<X> gnome-terminal

  1. Update it

  2. And then close it

$ qvm-shutdown debian-<X>
  1. Clone debian-X template
$ qvm-clone debian-<X> kali-rolling
  1. Check the name of currently used repository in /etc/apt/sources.list and current testing Debian release. Update repository list accordingly
# sed -i 's/<current stable>/<current testing>/g' /etc/apt/sources.list
# sed -i 's/<current stable>/<current testing>/g' /etc/apt/sources.list.d/qubes-r<X>.list

e.g. in this example we update buster stable repository to bullseye testing repository

# sed -i 's/buster/bullseye/g' /etc/apt/sources.list
# sed -i 's/buster/bullseye/g' /etc/apt/sources.list.d/qubes-r<X>.list

For installation based on Debian 10 stable, please note that the security repository of Debian testing has recently been renamed from <current testing>/update to <current-testing>-security. To account for that change, execute the following command.

# sed -i 's/bullseye\/updates/bullseye-security/g' /etc/apt/sources.list
  1. Update the template

Note: During execution of the update, read carefully list of packages to be removed. If it contains qubes-* packages, terminate operation and try to resolve qubes-* packages missing dependencies first.

  1. Copy the Kali GPG key from the DispVM to the new template:
$ qvm-copy kali-key.asc

The DispVM can now be turned off.

  1. Add the Kali GPG key to the list of keys trusted to authenticate packages:
# cat /home/user/QubesIncoming/dispXXX/kali-key.asc | apt-key add -

This command should return OK on a line by itself.

  1. Add the Kali repository
# cat <<EOF > /etc/apt/sources.list.d/kali.list
# Kali Linux repository
deb https://http.kali.org/kali kali-rolling main non-free contrib
EOF

  1. Update the template

  2. Ensure a terminal can be opened in the new template.

$ qvm-run -a kali-rolling gnome-terminal

Install the Kali tools

At this point you should have a working template and you can install the tools you need. Keep in mind that the tools you will install can easily take more than 10GB, so you will need to grow the size of the VM1
