It was discussed several time in the past, last I remember the issue is mainly with Windows guests,

There are some hints to solve it in this page:
http://serverfault.com/questions/624690/windows-guest-on-kvm-qemu-suffers-horrible-key-lag

(iirc, using a usb keyboard would solve it too)

I am not convinced at this point that the keypress-delay is problematic. Do you have a particular use case, or simply text typing?

thanks
