    I would say that in many cases running a multi kernel Hal when you have only 1 CPU doesn't have any noticable effect but your guest will not perform as well as it would with the correct hal.
    OH there is another issue which occures with non ACPI Hal mismatch situations where the guest will not be able to maintaintime, it will basicly loose 30 seconds each minute.
    What operating system is your guest session.
    Windows 2003 and XP will sort the HAL out them selves generally, WINnt is a bit of a mission and Win2k is a quick change.
