Development VM
To ensure compatibility across distribution, this project ships a wide range of development and tests VM images.
The test VMs can be built locally using cloud-init, packer on Qemu/KVM using Libvirt. No other hypervisor will be targeted for these tests. The files that generate these images can be found in the tests/packer directory.
The VMs are fully managed using a Justfile that provides an integration environment helper for apparmor.d.
Available recipes:
help # Show this help message
clean # Remove all build artifacts
...
[vm]
img dist release flavor # Build the VM image
create osinfo flavor # Create the machine
up osinfo flavor # Start a machine
halt osinfo flavor # Stops the machine
reboot osinfo flavor # Reboot the machine
destroy osinfo flavor # Destroy the machine
snapshots osinfo flavor # List all snapshots for a machine
snapshot osinfo flavor snapname # Snapshot a machine
restore osinfo flavor snapname # Restore a machine to a specified snapshot
delete osinfo flavor snapname # Delete a specified snapshot from a machine
ssh osinfo flavor # Connect to the machine
mount osinfo flavor # Mount the shared directory on the machine
umount osinfo flavor # Unmout the shared directory on the machine
list # List the machines
images # List the VM images
available # List the VM images that can be created
...
Build variables available:

Requirements¶
Note
You may need to edit some settings to fit your setup:
- The default ssh key and ISO directory in
tests/packer/variables.pkr.hcl
Build¶
One can see the available images by running:
Distribution Release Flavor
archlinux - gnome
archlinux - kde
debian 13 gnome
debian 13 server
debian 13 test
opensuse - gnome
opensuse - kde
ubuntu 24.04 server
ubuntu 25.05 desktop
ubuntu 25.05 kubuntu
ubuntu 25.10 test
...
A VM image can be build with:
The image will then be showed in the list of images:
The VM can then be created with:
And connected to with:

Credentials
The admin user is: user, its password is: user. It has passwordless sudo access. Automatic login is not enabled on DE. The root user is not locked.
Directories
All the images come pre-configured with the latest version of apparmor.d installed and running in the VM. The apparmor.d project directory is mounted as /home/user/Projects/apparmor.d
Usage
On all images, aa-update can be used to rebuild and install the latest version of the profiles. p, pf, and pu are two pre-configured aliases of ps that show the security status of processes. htop is also configured to show this status.
