High CPU load when guest (WinXP) is idle on Ubuntu 8.04/x64

[bernroth]

Hello all,
I just would like to say that my guest is not running any database server.
Maybe another program uses these calls, producting the high CPU load.
Any way to find out which process to blame?

Best regards,
Bernhard

could USB be to blame?

[bernroth]

Yes! As soon as I disable or disconnect all persistent USB devices, the load drops to 5%. Disabling USB has the same effect. Is this a known issue?
What can be done to solve it? I require the USB key to make some software work
Best regards,

Is this a known issue?

This is with the XP guest install running but more or less idle. I have no USB enabled in the Guest, But my mouse and WiFi are connected via USB to the host, openSUSE 11.1. 3d acceleration is enabled (auto) I have guest additions loaded to the guest. In case there are problems, the above shows that VBox is consuming 93% of CPU!
The VBox is v2.1.4

Have anyone tried my temporary solution of running dummy vm with minimal amount of ram, i guess to force vbox use load balancing?
