Do you have a reason for not running OpenSuSE 10.3 in Paravirtualized mode instead of in an HVM?

Hi there

I have an opensuse10.3 domU running as a HVM guest on xen 3.2.1
No I would like to install the PV drivers to get better performance on
disk IO.

The Problem is that I do not manage to compile the drivers:
