libvirt users - Jan 2011 - Windows guest eats as many CPU as available

Hello,

I run Debian on my Laptop Lenovo X60s (with VT).
I've created a Windows-XP as well as a Windows-Vista guest on it.
Both, XP as well as Vista, eats as many CPU as available.
Therefore the CPU always has high load and will never reduce cpu-frequenz or 
ventilator.

Did this works as designed or should I modify something?

Thanks in advance
Matthias

When my Windows 2003 guest  is idling (0% vcpu usage), host  os is
idling too ( up to 3% cpu).
Did you check the guest os and find out the process which is eating
your cpu time?

No, there is only the idle-process ("Leerlaufprozess" in german) which
need
96% of the CPU in an average.
In the same time KVM needs nearly 100% of my Host-CPU.
