Hello everyone,
 
I was trying to run Windows 8.1 with QEMU and OVMF(UEFI) bios. And I was 
success in running Windows 8.1 VM with QEMU and OVMF(IA32) BIOS.
 
However, when I use USB 3.0 controller (xhci, "-usb -device 
nec-usb-xhci,id=xhci" option) of QEMU, OVMF bios doesn't work and only show 
black screen.
 
I was using these QEMU command and OVMF.fd (IA32) files from 
http://sourceforge.net/projects/edk2/files/OVMF/
$ qemu-system-x86_64
    -enable-kvm
     -cpu host,+sep,+nx,+pae,+sse2
     -m 1024
     -smp sockets=1,cores=4,threads=1
    -drive id=drive1,if=none,media=disk,file=/devel/images/uefi/win8_uefi.qcow2
     -device virtio-blk-pci,drive=drive1,bootindex=2
    -usb -device nec-usb-xhci,id=xhci
    -bios /devel/images/OVMF_32.fd
 
Is there any problem when I use the xhci controller of QEMU with OVMF? or Does 
OVMF not support USB 3.0? 
 
Thanks,
/Je-Min Kim
