but if the middle level is present and it's not the large mapping,
this check is skipped.


Well, in the description, it looked like everything was using small
pages (in kvm, level=1 means PTE level, we need to change this one
day).  Please describe again and say exactly when the guest or host uses
large pages.

Avi, sorry for my poor English, i not mean "everything was using small", i don't
know where cause you confused :-(

Well, LVL1 got me to assume those are small pages.

Can you explain more precisely? Use the processor terms like PTE and PDE. Don't worry about your English :)
