From 702cbdc46b118b1622edeeaa01a22f7af9776388 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Kamil=20Szcz=C4=99k?= Date: Sat, 17 Aug 2024 15:26:15 +0000 Subject: [PATCH] hw/i386/pc: Ensure vmport prerequisites are fulfilled MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Since commit 4ccd5fe22feb95137d325f422016a6473541fe9f ('pc: add option to disable PS/2 mouse/keyboard'), the vmport will not be created unless the i8042 PS/2 controller is enabled. To avoid confusion, let's fail if vmport was explicitly requested, but the i8042 controller is disabled. This also changes the behavior of vmport=auto to take i8042 controller availability into account.
