Vagrant with libvirt on Debian testing

Install prerequisites:

sudo apt install vagrant-libvirt libvirt-daemon-system

Add current user to libvirt group:

sudo usermod --append --groups libvirt $USER
# should return libvirt
groups | grep -o libvirt

Add some images:

vagrant box add bento/centos-7.9 # this will not work at libvirt
vagrant box add debian/buster64

Start your Vagrant environment:

vagrant init debian/buster64 # it will create a Vagrantfile in current dir that can be edited
vagrant up --provider=libvirt
vagrant ssh
