After some digging, it seems that windows itself is responsible for that bug. On international keyboards, it tend to send "Ctrl" and "Alt" instead of "AltGr" keycode.
A possible patch would be to add an option to QEMU command line to handle Ctrl and Alt keystrokes being pressed at the same time as AltGr keystroke. -- You received this bug notification because you are a member of qemu- devel-ml, which is subscribed to QEMU. https://bugs.launchpad.net/bugs/1101210 Title: qemu 1.4.2: usb keyboard not fully working Status in QEMU: Confirmed Bug description: When using the usb keyboard, I can't type the | character. I'm using german keyboard layout (de) on the host and inside the guest. As a guest OS, I use Linux (e.g. a recent KNOPPIX cd). To obtain the | character on a german keyboard, I need to press AltGr + the < or > key, i.e. the key right to the left shift. The qemu command line is something like this: ./qemu-system-i386 -device pci-ohci -device usb-kbd I also tried ./qemu-system-i386 -usb -usbdevice keyboard with the same effect.
