  /usr/libexec/qemu-kvm -M pc -m 2G -smp 2 -cpu host -usb -device usb-tablet -device virtio-scsi-pci,bus=pci.0,addr=0x5,id=scsi0 -device scsi-hd,bus=scsi0.0,drive=drive-ide0-0-0,id=scsi2,bootindex=1 -drive file=win81-32.raw,format=raw,if=none,id=drive-ide0-0-0,werror=stop,rerror=stop,cache=unsafe,serial=abcdefghtfdfdsfsdfsdfsdfsdfdsf000 -netdev tap,id=hostnet0,script=/etc/qemu-ifup -device e1000,netdev=hostnet0,mac=00:52:4f:65:25:31,id=net0 -uuid 4870b5fd-65d1-488a-9333-3c4e095285b0 -rtc-td-hack -no-kvm-pit-reinjection -chardev socket,id=a111,path=/tmp/monitor-win2012-serial,server,nowait -mon chardev=a111,mode=readline -vnc :4 -vga cirrus -monitor stdio -drive file=testscsi.raw,if=none,id=drive-scsi0-0-0,if=none,media=disk,cache=writeback,format=raw,werror=stop,aio=native,readonly=off -device scsi-hd,bus=scsi0.0,drive=drive-scsi0-0-0,id=scsi1,scsi-id=254,lun=10 -drive file=en_windows_8_1_enterprise_x86_dvd_2971902.iso,if=none,media=cdrom,format=raw,id=drive-ide1-0-1 -device ide-drive,drive=drive-ide1-0-1,id=ide1-0-1,bootindex=2 -drive file=/home/virtio-win-86-rng.iso,if=none,media=cdrom,format=raw,id=drive-ide1-0-2 -device ide-drive,drive=drive-ide1-0-2,id=ide1-0-2 -fda 86-block-32.vfd -qmp tcp:0:3333,server,nowait -device virtio-scsi-pci,id=bus2 -device scsi-hd,bus=bus2.0,drive=scsi-disk5,id=disk5,serial=test5 -drive file=disk5.raw,if=none,media=disk,format=raw,rerror=stop,werror=stop,cache=unsafe,aio=native,id=scsi-disk5
2.downgrade virtio scsi driver from build 86 to build 75 or 83
  from Device Manager -> downgrade the data disk virtio scsi driver and one message will tell you restart machine,please click "yes"
