Summary: 100# Idle CPU usage with Windows Guest

Initial Comment:
Hi, im experience a very laggy experience when having Windows XP running as guest. ( as in takes time to show icons when the Windows background is visible )

Im running a Gentoo with Linux 2.6.20 vanilla 64bit kernel + kvm-12

Windows host is a normal Windows XP, which i normally boot when need to use the graphic card. 

A symptom of the guest is that it use 100% CPU at all times, and under Task manager in Windows, it's saying it's explorer ( and task manager ) that is using it. When booting Windows XP native, it's just idling. 

I start KVM with "./qemu-system-x86_64 -hda /dev/sda -boot c -m 512"

What information can also be used to determine the problem?
