Re: [Xen-users] CPU Usage
Have you checked that you've got the ACPI Multiprocessor driver in use in
Windows?
In Device Manager, under the Computer node you should have 'ACPI Multiprocessor
PC'. If instead you're seeing 'Uniprocessor PC' or similar, just update the
driver and select the multiprocessor one instead.
GPLPV is not needed for this, but I'd really recommend installing them for
anywhere decent I/O performance.
