+# Initial setup of debian VM with virt-customize + netplan

+This method consist of using the debian generic cloud image and just customizing it before first boot with the [virt-customize](https://man.archlinux.org/man/virt-customize.1.en) util.
+
+Then for the network config, we will be using [netplan](https://netplan.readthedocs.io/en/stable/).
