Long description

The figure shows a rectangular block containing six columns labeled from left to right as follows. Blank, Level 1 offset, Level 2 offset, Level 3 offset, Level 4 offset, and page offset. The boundary of each column is numbered as 63, 48 47, 39 38, 21 20, 12 11, 0. The level 1 offset column is pointed to the first adder labeled Guest pointer to the level 1 page table. The adder points to a block using an arrow labeled Guest pointer to the entry in the level 1 page table. The block represents Lookup in nested page tables. An arrow from this block points to a vertical block which again points to the second adder. An arrow from the level 2 offset also points to this adder. The adder points to another block representing Lookup in the nested page table. An arrow points from this to a vertical block and then again an arrow from this vertical block points outward and continues.
