From 746f244d9720233f42a5a5745e28a4fac9fe8395 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Philippe=20Mathieu-Daud=C3=A9?= Date: Tue, 21 Jan 2020 00:51:56 +0100 Subject: python/qemu/machine: Allow to use other serial consoles than default MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Currently the QEMU Python module limits the QEMUMachine class to use the first serial console. Some machines/guest might use another console than the first one as the 'boot console'. For example the Raspberry Pi uses the second (AUX) console. To be able to use the Nth console as default, we simply need to connect all the N - 1 consoles to the null chardev. Add an index argument, so we can use a specific serial console as default.
