This leads me to believe the problem is with vbox 1.6.0 itself, and not with my hardware. I also installed a winxp guest for testing purposes to see if I have the same problem there, and the keyboard works just fine in the winxp guest under vbox 1.6.0. So, the problem seems to be with the gnu/linux guest only. I've attached a log of my gnu/linux guest vm running under vbox 1.6.0. The problem was so bad that I couldn't even type root my_password in order to login, and shut down the machine properly via halt. I had to use ""vboxmanage controlvm debian poweroff""." defect closed GUI VirtualBox 1.6.0 fixed sluggish guest keyboard other Windows
