Hej folks,

While checking out why our windows 2008 domU is 'slow' according to my boss, I 
stumbled upon something interesting:
- The windows 2008 server (using GPLPV drivers claims to have 
nearly no cpu usage, in multiple places like the taskmanager, process explorer 
etc I see only 5-10% cpu usage at max.
- In xentop I see the win2008 domU constantly using 150-200% cpu?!

Can someone explain this huge difference?

The windows domU has 8 vcpus assigned to it along with 16GB RAM, along with an 
LVM backed disk. Nothing special afaik.  Any hints?
