This one is mainly written for those that want to adapt it. If you do not touch at all you obtain a customizable running VM.

VMkeyboard the console keyboard (if you do not touch this line it will be the same as your host machine).

VMlocale the localization (if you do not touch this line it will be the same as your host machine).

VMtimezone the timezone (if you do not touch this line it will be the same as your host machine).

VMusername the name of the initial user.

VMname the name of your VM (as in the VirtualBox dashboard).

Customizing the scriptĬustomization is carried out by editing the bash variables on top of the script. Surprise, it is faster than the procedure based on the mini.iso.

Using a mix of VBOxMangage commands and the cloud-init tools you obtain a tasksel dialog to proceed with you customization. You have many options here about the image format to use: I refer to the.

So I decided to find a way to do without the mini.iso, and I wrote this script that takes to the ''tasksel'' step starting from a cloud image in the ubuntu repository. An askubuntu post on the topic (there are several) is here. A distribution of the mini.iso for Ubuntu 20.04 is indeed still available here, but there is no guarantee that its availability will continue after Focal Fossa. This is a bad news for those (like me) that formerly used this distribution to produce lightweight virtual machines for development, teaching, testing, etc. The mini.iso for the Ubuntu distribution is legacy since version 20.04LTS (Focal Fossa). Living without the Ubuntu mini.iso (in VirtualBox)
