Hi,

I'm facing the same problem here.

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

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

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

Regards, Elias P.
