L0 = bare metal machine
L1 = VM on bare metal
L2 = VM on VM

First, ensure virtualization is enabled on L0 as described here: https://docs.fedoraproject.org/en-US/quick-docs/using-nested-virtualization-in-kvm/#proc_enabling-nested-virtualization-in-kvm

Next, launch L1 with the following Vagrant config (or an equivalent directly on the hypervisor):

Vagrant.configure("2") do |config|
  config.vm.box = "generic/ubuntu1604"
