Installed Arch Linux in VirtualBox under Windows 7 host and on each boot, you receive the error message:
[ 0.000000] Fast TSC calibration failed.
I know that it is not critical, but are unable to live in peace, while the message is there! :) I would be very grateful for any help!
PS the Option of changing the GRUB config file with all possible variations of the parameters clocksource
yielded no result!
