For a Windows guest, try using the "Advanced Configuration and Power Interface (ACPI) PC" HAL. The forum has details on how to do that for XP, search forums.virtualbox.org for HALu. For Linux, try turning the VirtualBox IO APIC setting off. (Both of these also make the VM use only one CPU/core.) For Windows guests, use VirtualBox 3.1.4, or turn off any Windows firewall in the guest. ------------------------------------------------------------------------------ Download Intel® Parallel Studio Eval Try the new software tools for yourself.
