Setting up Vagrant with libvirt (Fedora 40)

# dnf install qemu-kvm libvirt libguestfs-tools virt-install rsync vagrant
# systemctl enable libvirtd && sudo systemctl start libvirtd
# vagrant plugin install vagrant-libvirt

$ vagrant box add fedora/40-cloud-base --provider=libvirt

$ mkdir vagrant-demo && cd vagrant-demo
[user:~/vagrant-demo]$ touch Vagrantfile

Vagrant.configure("2") do |config|
  
  # image to use
  config.vm.box = "fedora/40-cloud-base"

  config.vm.provider :libvirt do |libvirt|

    libvirt.cpus = 2
    libvirt.memory = 2048

    # the default qemu session connection cannot create networks
    # either disable it, like so:
    libvirt.qemu_use_session = false
    # or specify the connection uri:
    # libvirt.uri = 'qemu:///system'

  end

  config.vm.hostname = "localhost"

  # Mounting directories
  # (this is the implicit default, manually disabled)
  config.vm.synced_folder "./", "/vagrant", disabled: true

  # Networking
  # VAGRANT GUESTS ARE INSECURE BY DEFAULT
  # DO NOT EXPOSE THEM TO UNSECURED NETWORKS

  # config.vm.network "forwarded_port", guest: 443, host: 4433
  #
  # config.vm.network "public_network", ip: "192.168.1.1", hostname: true
  # hostname: true adds the hostname and interface IP to /etc/hosts
  #
  # config.vm.network "public_network"
  # no IP specified? DHCP will be used.
  #
  # By default, public networks will bridge to the
  # network interface on the host machine. If more
  # than one exists, Vagrant will ask which to use.
  # Or specify the interface like so:
  #
  # config.vm.network "public_network", bridge: "eno1"
