RE: [Xen-users] Running Xen 2.0 for Counter Strike: Source

["Bart van den Heuvel" <bart@xxxxxxxxxx>]

I have recompiled the kernels, both dom0 and domU. Counterstrike comes in
a compiled form (silly enterprises still do that :-)

All is wel and i got the change to compile in the bigmem option! So i'm
very happy there. I can now use more mem for my virtual servers... But
thats where the happyness stops!

Instead of a performance upgrade fps is now steady on 1, so the 1000 hz
options made the fps value go from 50 to 1 instead of a higher value.

I'm running like this for a few hours... Maybe more inspiration will come
to me.

Regards,

Bart
