The C API of libvirt is well documented and one can easily understand how the virNetworkGetDHCPLeases function should be called. However, it is less straightforward with the python libvirt module despite the libvirt development guide. The example from the sources shows the corresponding python method is DHCPLeases
conn = libvirt.open("qemu:///system")
net = conn.networkLookupByName("default")
leases = net.DHCPLeases()
But how did virNetworkGetDHCPLeases become DHCPLeases?

Even when nonprofit organizations publish their financial records (such as the mediawiki foundation), the work done by volunteers has an estimated financial value of zero. These organizations will however unanimously claim that volunteers are an essential part of society and have a very special place in their heart. While most of them are sincere, observation tells us a different story:
- In the context of fundraising, volunteers are second class citizens compared to organizations who donate money
- A lack of transparency excludes volunteers from decisions and day to day work
How is it that one year of a volunteer who is worth $60,000 on the market is considered less valuable than a $60,000 grant used to pay the salary of the same person?

The Debian GNU/Linux cloud images can conveniently be used out of the box with the following:
$ wget -O debian.qcow2 https://cloud.debian.org/images/cloud/buster/20201214-484/debian-10-generic-amd64-20201214-484.qcow2
$ virt-sysprep -a debian.qcow2 --run-command 'dpkg-reconfigure --frontend=noninteractive openssh-server' --ssh-inject debian:file:$HOME/.ssh/id_rsa.pub
$ virt-install --connect qemu:///system --boot hd --name debian --memory 1024 --vcpus 1 --cpu host --disk path=$(pwd)/debian.qcow2,bus=virtio,format=qcow2 --os-type=linux --os-variant=debian10 --graphics vnc --noautoconsole
$ virsh --connect qemu:///system domifaddr debian

However, 2GB for the root file system may not be enough: virt-resize and virt-rescue should be used to expand it.

Enough is a software released as a pypi package and a docker image to maintain an infrastructure composed of multiple machines, physical or virtual. In other words, it is an infrastructure as code based on Ansible and OpenStack. In addition it is built exclusively on Free Software, primarily because it helps with backdoors and viruses. These two properties combined create a unique opportunity to onboard volunteers devops willing to help nonprofit organizations defending whistleblowers.

After four years volunteering for non-profits (from the Freedom of the Press Foundation working on SecureDrop to the Maison des Lanceurs d’Alerte working on Enough), I find myself looking for paid work. It is a challenge, mainly because I do my best to only use Free Software and only write Free Software. The last part (writing Free Software) has become increasingly easier in the past twenty years: there are hundreds of companies willing to pay a full time developer to exclusively contribute to a Free Software code base. The first part (using Free Software) is still very difficult.
