Bug report 625716 suggests
kvm -usb \
-drive file=filename,if=none,id=b,boot=on \
-device usb-storage,drive=b
(the key point is boot=on subparameter)
So I tried
root:~ /usr/bin/qemu-system-x86_64 -m 2000 -usb -drive
file=/dev/sde,if=none,id=b,boot=on -device usb-storage,drive=b -enable-kvm
but it failed with error code 0xc00000e9
Thanks,
Kingsley
