Hi,

I'm facing the same problem here.

A Windows XP (SP3 + all current Updates) which uses constantly ~95% CPU on=
=20
each core.

I've already tried:
=2D Using only 1 core
=2D Replacing the HAL in Windows
=2D Using another KVM version
=2D Using different timer options for KVM

I'm currently on KVM-85 where the problem still exists.

Regards, Elias P.
