If it's Windows 7:

otherwise I would check ACPI settings.


It's Windows server 2003 32-bit. I haven't installed any GPLPV drivers
(Should I?)

I checked in device manager on the DomU and it indeed shows the 2 CPU
cores:
"Intel Xeon CPU"
"Intel Xeon CPU"

(I've ommited the model and speed just to keep it simple)

However the task manager only shows one graph

Any Ideas?

Thanks

If you disable "One graph per CPU" in the view options, you only see
one graph, even with two cores.

Can you tell I'm a Linux guy?? :)

Thanks Bart for your help

BTW, does GPLPV increase disk performance by much?

Thanks

I am too, unfortunately you bump into these all the time.

I remember seeing a distinct raise in performance for the disks after installing the drivers. I install them anyway, just for the Shutdown Monitor. Doesn't hurt, though some get problems after.

If you really want to be sure, there are commercial drivers available as well by for instance Novell.
