High CPU load in VB 3.2

[inri]

I installed VB 3.2.0 on Ubuntu 10.04 LTS Server (64 Bit). The Virtual Machine is Windows Server 2008 (32 Bit) with one CPU assigned.
Even if the CPU-Load in Windows 2008 is nearly 0, i got a CPU load of 50%-65% on the linux host for VBoxHeadless.

Here i have the vminfo of the Machine:

Has anyone an idea, what's the reason for the high cpu-load?

Same problem for me.
With linux guest cpu and ram
really high.

Post the guests log file (as an attachment)

Which log file do you mean? Where can i find it?

[Perryg]

/home/<user name>/.VirtualBox/Machines/<name of machine>/Logs/VBox.log

[inri]

Here the log-file. I hope it can help you in finding the "troublemaker".

I am running VirtualBox 3.2.0 with a Fedora 13 64 bit Host and a CentOS 5.4 32 bit Guest. I have a Intel Quad 6600. Since upgrading to 3.2.0, one CPU goes to 100% as soon as I start the Guest.

From earlier problems with high cpu and time of day, I boot CentOS guest machines with divider=10 and nolapic_timer as kernel parameters.

Neither did any good with the current 3.2.0 problem. However, at the suggestion of another post I turned off Nested Paging. My Q6600 supports VT-x so I turned that off too.

The Guest is running and the Fedora System Monitor is reporting all 4 CPUs are running in the range of 1 to 3% cpu.

SOLVED.

I upgraded to VB 3.2.4 and now everything works fine with an avarage CPU-Load of appr. 3-5%.

Thanks for all replys
