Whenever I try to switch from the nouveau driver to any nVidia driver (304, 310 or nvidia-current) and reboot my machine after selecting a driver Ubuntu boots with the following error:

[2.4556] kvm: disabled by bios
[2.4556] kvm: disabled by bios
[2.4556] kvm: disabled by bios

The numbers in front of the text are always something in the form of 2.xxx.

Is there anyone else experiencing problems? My graphics card is the nVidia GTX550 Ti

@stonedsquirrel I'm positive. If I use the nouveau driver everything works like a charm, except for games that is. – Kevin Nov 14 '12 at 16:08

I got rid of these errors by enabling CPU virtualizaton in the BIOS.
