Host OS: XP SP3
Guest OS: FreeBSD 7.2
Processor: C2D (CPU with 2 cores)

I use FreeBSD without X. FreeBSD consumes practically no resources when in idle. But in my host OS VB always consumes 100% of one core of my two core CPU. So it uses 50% CPU constantly!

Any solution suggested to repair this?

From other posts that have this problem.

To fix this, you have to build guest kernel with HZ=100 (kernel timer) and without tickless mode.

Thanks for advice.

This does the job.

echo kern.hz=100 >> /boot/loader.conf

So in /boot/loader.conf a line should be added kern.hz=100

Then reboot and CPU load in HOST OS is down to zero in idle. So no rebuilding kernel or other stuff just this line does the job!

Here is where i found where to put the line. Problem solved!

This worked perfectly, thank you.
