Version-Release number of selected component (if applicable): qemu-kvm-0.12.1.2-2.415.el6.x86_64 2.6.32-459.el6.x86_64 Steps to Reproduce: 1.boot guest with a virtio-scsi device(specified scsi-id and lun), such as: /usr/libexec/qemu-kvm -m 2G -smp 2 -monitor stdio -boot menu=on -vnc :11 -drive file=/home/RHEL-Server-6.5-64-virtio.qcow2,if=none,id=img,media=disk -device virtio-scsi-pci,id=scsi0 -device virtio-blk-pci,drive=img,id=sys-img -drive file=/home/juli/test1,if=none,media=cdrom,id=cdrom0 -device scsi-cd,drive=cdrom0,id=sys-cdrom0,bus=scsi0.0,scsi-id=0,lun=1 -S 2.hot-plug another scsi-cd device with the same existing "scsi-id=0 and lun=1". (qemu) __com.redhat_drive_add file=/home/juli/test2,id=test1 (qemu) device_add scsi-disk,drive=test1,id=sys-test1,bus=scsi0.0,scsi-id=0,lun=1 Fix included in qemu-kvm-0.12.1.2-2.432.el6 Reproduce this bug as follow version: # uname -r 2.6.32-452.el6.x86_64 # rpm -q qemu-kvm qemu-kvm-0.12.1.2-2.431.el6.x86_64 Steps: 1.Boot guest with -device virtio-scsi-pci,id=scsi0,bus=pci.0 -drive file=/usr/share/virtio-win/virtio-win.iso,if=none,media=cdrom,id=cdrom0 -device scsi-cd,drive=cdrom0,id=sys-cdrom0,bus=scsi0.0,scsi-id=0,lun=1 2.hot-plug another scsi-cd device with the same existing "scsi-id=0 and lun=1". (qemu)__com.redhat_drive_add file=en_windows_xp_professional_x64.iso,id=test1 (qemu)device_add scsi-cd,drive=test1,id=sys-test1,bus=scsi0.0,scsi-id=0,lun=1 Results: hot-plug successfully. And this operation will overlap the existing device. Verify this bug as follow version: # uname -r 2.6.32-452.el6.x86_64 # rpm -q qemu-kvm qemu-kvm-0.12.1.2-2.434.el6.x86_64 Steps as same as reproduce Results: (qemu) device_add scsi-cd,drive=test1,id=sys-test1,bus=scsi0.0,scsi-id=0,lun=1 lun already used by 'sys-cdrom0' Device 'scsi-cd' could not be initialized according to above test ,this bug fixed. *** Bug 1096590 has been marked as a duplicate of this bug. *** Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA.
