This tutorial leverages KVM. So you need to have a linux machine on which KVM is installed and running. Also this tutorial assumes that you have some experiences of KVM (i.e. creating and deleting VMs).
* [Virtual Machine Manager](https://virt-manager.org/): used to create VMs and Networks.
* [qemu-img](https://qemu.weilnetz.de/doc/qemu-doc.html#disk_005fimages): used to [image files](https://people.gnome.org/~markmc/qcow-image-format-version-1.html).
In this tutorial, [openSUSE Tumbleweed](https://en.opensuse.org/Portal:Tumbleweed) will be used as host PC, but in most cases there should be no problem caused by specific distributions or libvirt versions.
[tmux](https://github.com/tmux/tmux/wiki) can be used to run commands on multiple compute instances at the same time. Labs in this tutorial may require running the same commands across multiple compute instances, in those cases consider using tmux and splitting a window into multiple panes with `synchronize-panes` enabled to speed up the provisioning process.
> The use of tmux is optional and not required to complete this tutorial.
If you want to setup tmux like above, `ctrl+b` -> `"` twice, then `ctrl+b` -> `alt+2`.
> Enable `synchronize-panes`: `ctrl+b` then `shift :`. Then type `set synchronize-panes on` at the prompt. To disable synchronization: `set synchronize-panes off`.
