You can use a Vagrant to set up a development environment for Nomad. Vagrant is a tool for building and managing virtual machine environments.

It's often used sorta similar to minikube on the kubernetes side of things, but it can do quite a bit more than just creating a nomad dev setup.

libvirt

Unfortunately, it doesn't support QEMU/kvm out of the box. However, a plugin vagrant-libvirt exists to add support.\

On void I needed to install some packages first:
xi libxml2-devel libvirt-devel ruby-devel gcc

Then install the plugin:
vagrant plugin install vagrant-libvirt

Finally, create your virtual machine with:
vagrant up --provider=libvirt

NOTE: You might need to modify your Vagrantfile slightly to support libvirt. While following the nomad tutorial I needed to change this following line:
config.vm.box = "bento/ubuntu-18.04" # 18.04 LTS
to
config.vm.box = "generic/ubuntu1804" # 18.04 LTS\

You can find a list of images online that support libvirt:

connect

vagrant ssh

running script without root

You can use privileged: false to create a script that runs as the normal vagrant user rather than root.

Vagrant.configure("2") do |config|
  $script = <<-SCRIPT
  rbenv install 2.0.0-p353
  rbenv global 2.0.0-p353
  gem update --system
  yes | gem update
  gem install rdoc
  gem install rails pg
  SCRIPT

  config.vm.provision "shell", inline: $script, privileged: false
end
