CPU racing at 30% or more in Virtualbox

I have window 7 64 bit Lenovo i7 with 8gb ram and 160gb ssd. I have virtual box version 4.1.16 installed (most latest to my knowledge)

I want to install ubuntu 12.04 as a guest inside of virtualbox. I have tried a couple of times now. It installs and "works" but the cpu in the guest os with no applications running is between 30% and 100%. The host machine is running without any slow downs. I have tried all sorts of different settings from within ubuntu and on virtualbox. But ubuntu continues to race.

Has anyone experienced this? Any help would be appreciated.

Thanks

So my issues appears to have been being caused by NOT running in ubuntu 2d and a setting in the bios (VT-x). Once I changed the setting in the bios. The performance became drastically better and I also was then able to allow for 2 cpu's.

Thanks for all of your help.
