Well...  the guest OS has to run in protected mode, so there has to be a page 
table somewhere...  But you don't have to do anything fancy with it.

Is this for a custom guest?  The domain builder will give you a set of 
bootstrap pagetables - this might even be enough for your if your guest OS 
has tiny memory requirements.  If you need more, your guest should probably 
build one pagetable at startup that maps all of the available memory, then 
use that table for everything.

Does that answer your question?

Cheers,
Mark
