From 6ef4716cecdfa1b3794c1a33edba9840e1aa6b5f Mon Sep 17 00:00:00 2001 From: Markus Armbruster Date: Fri, 14 Jun 2013 13:15:01 +0200 Subject: vl: Clean up parsing of -boot option argument Commit 3d3b8303 threw in some QemuOpts parsing without replacing the existing ad hoc parser, resulting in a confusing mess. Clean it up. Two user-visible changes: 1. Invalid options are reported more nicely. Before: qemu: unknown boot parameter 'x' in 'x=y' After: qemu-system-x86_64: -boot x=y: Invalid parameter 'x' 2. If -boot is given multiple times, options accumulate, just like for -machine. Before, only options order, once and menu accumulated. For the other ones, all but the first -boot in non-legacy syntax got simply ignored.
