From f31d07d175b25ecca89f5d55dfdf2b55540e5e44 Mon Sep 17 00:00:00 2001
From: Gerd Hoffmann <kraxel@redhat.com>
Date: Fri, 31 Jul 2009 12:25:37 +0200
Subject: QemuOpts: switch over -device.

Make -device switch use the QemuOpts framework.
Everything should continue to work like it did before.

New: "-set device.$id.$property=$value" works.
