| Doc Text: |
Previously, when the data plane was in use, changing the target image of a virtual SCSI CD device caused the guest to terminate unexpectedly with a core dump. With this update, the virtio-scsi bus rejects SCSI CDs when the data plane is active, which prevents the crash from occurring. Note that this is a temporary solution, and a full fix to make the data plane and SCSI CD compatible will be provided in the future.

Fix included in qemu-kvm-rhev-2.6.0-28.el7_3.12 Verified, the problem has been resolved, so set its status to "Verified".
Test Env:
kernel version:3.10.0-514.el7.x86_64
qemu-kvm-rhev version: qemu-kvm-rhev-2.6.0-28.el7_3.12.x86_64
Test Steps:
1.Start guest with qemu cmd:
/usr/libexec/qemu-kvm \
-sandbox off \
-machine pc \
-nodefaults \
-vga cirrus \
-chardev socket,id=qmp_id_qmpmonitor1,path=/var/tmp/monitor-qmpmonitor1-20170614-233639-etu9X2zc,server,nowait \
-mon chardev=qmp_id_qmpmonitor1,mode=control \
-chardev socket,id=qmp_id_catch_monitor,path=/var/tmp/monitor-catch_monitor-20170614-233639-etu9X2zc,server,nowait \
-mon chardev=qmp_id_catch_monitor,mode=control \
-object iothread,id=iothread0 \
-drive id=drive_image1,if=none,snapshot=off,aio=native,cache=none,format=qcow2,file=/home/kvm_autotest_root/images/rhel74-64-virtio.qcow2 \
-device virtio-blk-pci,id=image1,drive=drive_image1,bootindex=1,bus=pci.0,addr=0x3 \
-device virtio-scsi-pci,id=scsi1,iothread=iothread0 \
-drive if=none,cache=none,media=cdrom,id=drive_cd,readonly=on,file=/home/kvm_autotest_root/iso/linux/RHEL7.4-Server-x86_64.iso \
-device scsi-cd,id=device_cd,drive=drive_cd,bus=scsi1.0 \
-device virtio-net-pci,mac=9a:43:44:45:46:47,id=idvMp6XX,vectors=4,netdev=id9qJxPT,bus=pci.0 \
-netdev tap,id=id9qJxPT,vhost=on \
-m 4096 \
-smp 6,cores=2,threads=1,sockets=3 \
-cpu host \
-vnc :0 \
-rtc base=utc,clock=host,driftfix=slew \
-enable-kvm \
-monitor stdio \
Test Result:
Start guest failed with error msg:
"qemu-kvm: -device scsi-cd,id=device_cd,drive=drive_cd,bus=scsi1.0: scsi-cd is not supported by data plane"
