That's fine; it just means there was nothing mapped at that address in the guest pagetables. If it gets that far, then it read the l2e OK.

What address are you using?
I am running xp as domu and using va 0xc0300000 where it maps its pde and i think this page should be present and mapped

Have you compared it to what a pagetable
walk inside the guest OS returns?
sir, can you be little descriptive here. I didn't get your point here.
