Subject: [Qemu-devel] [PATCH] qdev-monitor: device_add crashes on non-device driver name, fix
Date: Thu, 28 Nov 2013 17:02:24 +0100 [thread overview]
Message-ID: <1385654544-1774-1-git-send-email-armbru@redhat.com> (raw)
From: Markus Armbruster <armbru@redhat.com>
Watch this:
$ upstream-qemu -nodefaults -S -display none -monitor stdio
QEMU 1.7.50 monitor - type 'help' for more information
(qemu) device_add rng-egd
/work/armbru/qemu/qdev-monitor.c:491:qdev_device_add: Object 0x2089b00 is not an instance of type device
Aborted (core dumped)
Crashes because "rng-egd" exists, but isn't a subtype of TYPE_DEVICE.
Broken in commit 18b6dad.
