Description

After upgrading to 3.2.10 i get constant high CPU usage with Windows guest after login. Before login CPU usage drops to normal. Reducing video memory to 16MB fixes this problem. No video acceleration enabled.

But 3D acceleration enabled? Please attach a VBox.log file of such a VM session.

no 3D acceleration. After reconfiguring back to 32MB video no problem with CPU %. Possible explanation - restoring machine saved with 3.2.8 to 3.2.10. If problem repeats, i will collect logs.

Today 2010-11-02 high CPU usage repeated. After 2 tries with 100% CPU i reduced video mem to 16M and problem disappeared. Logs attached.
