From 13336606a5ef9d6beeb8c0763ac0a9d11c249cac Mon Sep 17 00:00:00 2001 From: Robert Foley Date: Wed, 1 Jul 2020 14:56:21 +0100 Subject: [PATCH] tests/vm: Added a new script for ubuntu.aarch64. MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit ubuntu.aarch64 provides a script to create an Ubuntu 18.04 VM. Another new file is also added aarch64vm.py, which is a module with common methods used by aarch64 VMs, such as how to create the flash images.
