[Qemu-devel] [PATCH] scsi: reset cdrom tray statuses on scsi_disk_reset

Subject: [Qemu-devel] [PATCH] scsi: reset cdrom tray statuses on scsi_disk_reset
Date: Thu, 16 May 2013 17:34:28 +0200

Tray statuses should be also reseted. Some guests may lock the tray
and after reset before any kernel is loaded the tray should be unlocked.

Also if you reset the real computer the tray is closed. We should
do the same in qemu.

This fix is already commited for IDE CD.
Check the commit a7f3d65b65b8c86a5ff0c0abcfefb45e2ec6fe4c.
