It doesn't even make sense if interpreted as keyboard scancodes - 00 is reserved and ff is an error condition.Tomasz,Can you provide a recipe on how to reproduce this?
I used it with KVM, but it doesn't look KVM specific. I'll see if it happens with "pure" Qemu.
To reproduce: - start a guest; connect to VNC- type on the keyboard (just tap as much keys as you can) as you see BIOS, bootloader, Linux booting - if it didn't work on the first time, reboot the guest, type on the keyboard, change windows with your mouse etc. (make the VNC window "always on top" usually helps to have focus)
I can reproduce it almost always. -- Tomasz Chmielewski http://wpkg.org
