In any case, you'll have to rewrite things that aren't fully virtualized by Xen. This mainly includes memory management and interrupt handling. For Dom0, you should be able to use the same drivers without modification (not sure though, don't have much experience with Dom0) but you'll need to write the frontend/backend drivers for virtual devices. For DomU, you'll have to write drivers for virtual console, virtual disk and virtual NIC. Regards, Mathieu
