Subject: [Qemu-devel] Crash when deleting the diag288 watchdog
Date: Wed, 16 Aug 2017 07:05:37 +0200 [thread overview]
Message-ID: <451ff313-11c5-9f67-d7f1-a606c02efc79@redhat.com> (raw)
Hi,
I recently noticed that QEMU abort()s if you try to remove the diag288
watchdog. For example:
$ qemu-system-s390x -nographic -nodefaults -S -monitor stdio
QEMU 2.9.92 monitor - type 'help' for more information
(qemu) device_add diag288,id=x
(qemu) device_del x
**
ERROR:/home/thuth/devel/qemu/qdev-monitor.c:872:qdev_unplug: assertion
failed: (hotplug_ctrl)
Aborted (core dumped)
This is ugly, can we fix this somehow? For example, should the diag288
device be hot-pluggable at all, or can it only be used via the
"-watchdog" parameter instead? In the latter case, we could simply mark
the device with "user_creatable = false", I guess?
Thomas
