Hi all, Tl;dr: Virt-Lightning uses libvirt, cloud-init and libguestfs to allow anyone to quickly start new VM. Very much like a container CLI interface, but locally. -> https://github.com/virt-lightning/virt-lightning To validate my Ansible roles, I was looking for a way to quickly start and stop my test environments. I was looking for an experience similar to what we have with the containers. Virt-lightning takes a distribution name as main input. The output is the IP address of a freshly deployed VM on which I can run my tests. Virt-Lightning uses master QCOW2 images with backing file and avoid the use of DHCP, this to speedup up the first boot. The configuration is done by cloud-init. The whole deployment is rather fast. For instance, I can deploy 3 VM in 25s (Lenovo T580). cloud-init is used to create the user account, inject the SSH keys, prepare the network configuration and resize the file system.
