I have a dualboot system, Ubuntu and WinXP. I wanted to run my existing XP installation as a virtual machine under Ubuntu, so I installed Virtualbox, and followed the instructions on this page: http://www.virtualbox.org/wiki/Migrate_Windows
Everything went well (except a few glitches which I handled), XP started just like expected in Virtualbox and I saw the welcome screen, however I couldn't log in because neither mouse not keyboard were recognized. I couldn't install guest additions because...well, I couldn't login.
So, I rebooted the machine on XP, I installed guest additions (not on Virtualbox copy of the XP installation, but on the actual XP installation), rebooted on Ubuntu again, removed the XP virtual machine and repeated everything to create a new virtual machine from the existing XP installation on disk. But that didn't help either; mouse and keyboard are still not recognized.
Keyboard actually works until I see XP welcome screen on virtualbox. For example, when I boot the virtual machine from XP cd, I can use the keyboard. Only after XP boots, keyboard (and mouse) does not work. I also did a clean installation of XP as another virtual machine and it had no such problems.
So, the question is... how can make the keyboard and mouse work? Is there any way to install the drivers on Recovery Console? Or, can I install the required drivers by booting the virtual machine using a live linux cd and accessing the windows disk?
