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 template for security and privacy critical tasks is not recommended.
- Kali Linux distribution is a rolling distribution based on Debian testing release, so it will always have a newer software base than available in the Qubes OS Debian template. Keep in mind that this may result in problems (especially in regard to package dependencies) not covered by this tutorial.
From the official ISO file
Only use this method if you want the full Kali GUI (desktop, fancy menus, etc.). It comes at the cost of much greater resources consumption.
- Download the Kali ISO
- Create a new HVM
- Start the HVM with attached CD/DVD
$ qvm-start <hvm-name> --cdrom <vm-name>:/home/user/Downloads/<iso-name>.iso
From a Debian template
This is the recommended method. Easier to maintain and less demanding on resources, but you won’t have the full Kali GUI.
If you need to install custom kernel modules (wifi drivers, …) you need to use the kernel provided by Kali instead of the kernel provided by Qubes, see Managing VM Kernel.
The steps can be summarized as:
- Install Qubes stable Debian template
- Upgrade from Debian
stable
to Debiantesting
for Qubes repositories - Add
testing
andsecuritytesting
Qubes repositories - Replace the content of
/etc/apt/sources.list
file with the Kali repository - Update the template
Get Kali Linux PGP 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. In order to obtain a trusted fingerprint, check its value against multiple sources. Then, check the keys you download against your trusted fingerprint.
This step is required since by (security) default 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.
- Retrieve the Kali Linux PGP key using a DisposableVM.
$ gpg --keyserver hkps://keys.gnupg.net --recv-key 44C6513A8E4FB3D30875F758ED444FF07D8D0BF6
$ gpg --list-keys --with-fingerprint 44C6513A8E4FB3D30875F758ED444FF07D8D0BF6
$ gpg --export --armor 44C6513A8E4FB3D30875F758ED444FF07D8D0BF6 > kali-key.asc
-
DO NOT TURN OFF the DisposableVM, the
kali-key.asc
file will be copied in the Kali Linux template for a further step. -
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.
- (Optional) Check for latest Debian stable template and install it (if not already done)
# qubes-dom0-update --action="search all" qubes-template-debian
# qubes-dom0-update <latest Debian template>
- Clone
debian-X
template
$ qvm-clone debian-<X> kali-rolling
- Check the name of currently used repository in
/etc/apt/sources.list.d/qubes-r<X>.list
and current testing Debian release. Update repository list accordingly
# 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.d/qubes-r<X>.list
- Enable the QubesOS
testing
andsecuritytesting
repositories
In /etc/apt/sources.list.d/qubes-r<X>.list
, enable the testing
and securitytesting
repository.
We do that to reduce the 'dependency hell' between Qubes repository and Kali repository.
- Copy the Kali PGP key from the DisposableVM to the new template:
$ qvm-copy kali-key.asc
The DisposableVM can now be turned off.
- Add the Kali PGP 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
.
- Replace Debian repositories with Kali repository
# echo 'deb https://http.kali.org/kali kali-rolling main non-free contrib' > /etc/apt/sources.list
- Replace
gcc8
to work around a dependency issue
# apt-get remove libgcc-8-dev && apt-get install libc6-dev
Note: This kind of dependency issue will pop up and disappear without notice. Such issues arise because of the differences of dependencies in packages from the Kali repository, the Qubes testing repository and the Debian testing repository. So this step [step 8] is currently needed. But it will not always be the case.
- Update the template
Note: During execution of the update, carefully read list of packages to be removed. If it contains qubes-vm-dependencies
package, terminate operation and try to resolve missing dependencies first. For other qubes-*
packages, it is up to you to decide if you need them.
- 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.
You can find a list of Kali Linux Metapackages
here
Keep in mind that the tools you will install can easily take more than 10 GB, so you will need to grow the size of the VM system storage.
