parallels Packer (arm64)

A simple Packer + Vagrant install of Ubuntu 20.04 (Focal Fossa) LTS server for arm64, to run from my M1 Mac on Parallels Pro (17.1). Currently on MacOS Monterey.

Packer will run the ansible playbook.yml before the machine is shutdown and exported.

The installation is automated by cloud-init (which reads user-data). The file meta-data just needs to be an empty text file (you need to create this - no blank files or folders allowed in gists).
