Porting an OS to Xen is a bit vast. The bare-minimum should not take 
long depending on what arch/guest you are targeting, but this can add up 
when porting PV drivers.
Below a few question to try to have a better picture:
   - What architecture are you targeting?
   - What type of guest (e.g PV, PVH, HVM)?
   - What para-virtualized devices do you expect to expose to your guest?

Cheers,
