virtio-win.iso.el6

How reproducible:
100%

Steps to Reproduce:
1.Boot a guest with following qemu cli:
/usr/libexec/qemu-kvm \
    -name 'avocado-vt-vm1' \
    -machine pc  \
    -nodefaults  \
    -vga qxl \
    -device ich9-usb-ehci1,id=usb1,addr=1d.7,multifunction=on,bus=pci.0 \
    -device ich9-usb-uhci1,id=usb1.0,multifunction=on,masterbus=usb1.0,addr=1d.0,firstport=0,bus=pci.0 \
    -drive id=drive_image1,if=none,aio=native,cache=none,format=qcow2,file=/root/win2016-64-virtio.qcow2 \
    -device virtio-blk-pci,id=image1,drive=drive_image1,bootindex=0,bus=pci.0,addr=04 \
    -drive id=drive_data1,if=none,aio=native,cache=none,format=qcow2,file=/root/data1.qcow2 \
    -device virtio-blk-pci,id=data1,drive=drive_data1,bus=pci.0,addr=05 \
    -device virtio-net-pci,mac=9a:e3:e4:e5:e6:e7,id=idY87fGi,vectors=4,netdev=idjQ51hm,bus=pci.0,addr=06 \
    -netdev tap,id=idjQ51hm,vhost=on,script=/etc/qemu-ifup,downscript=/etc/qemu-ifdown \
    -m 2048 \
    -smp 2,maxcpus=2,cores=1,threads=1,sockets=2  \
    -cpu host \
    -drive id=drive_cd1,if=none,snapshot=off,aio=native,cache=none,media=cdrom,file=/root/en_windows_server_2016_x64_dvd_9327751.iso \
    -device ide-drive,id=cd1,drive=drive_cd1,bootindex=1,bus=ide.0,unit=0 \
    -drive id=drive_virtio,if=none,snapshot=off,aio=native,cache=none,media=cdrom,file=/root/virtio-win.iso.el6 \
    -device ide-drive,id=virtio,drive=drive_virtio,bootindex=2,bus=ide.1,unit=1 \
    -device virtio-balloon-pci,id=balloon0,bus=pci.0,addr=0x9 \
    -device usb-tablet,id=usb-tablet1,bus=usb1.0,port=1  \
    -spice seamless-migration=on,port=5901,disable-ticketing \
    -monitor stdio \
    -device usb-kbd \
    -qmp tcp:0:8881,server,nowait \
    -rtc base=localtime,clock=host,driftfix=slew  \
    -boot order=cdn,once=d,menu=off,strict=off \
    -enable-kvm \
2.Create a txt document in vm, then turn on Caps-Lock in keyboard, then input some characters in guest.

Actual results:
(1)After turning on Caps-Lock in keyboard, can't input uppercase characters in guest, "\"and lowercase characters was got insteading  uppercase in guest.for example, when input "AA", the result is "\aa" in guest. 
(2)When sendkey "shift+a" there will got "A" in guest
 (qemu) sendkey shift-a
 ---get "A" in guest

Expected results:
(1)After turning on Caps-Lock in keyboard, can input uppercase characters in guest.
