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?
