Three-level pagetables will let UML have more than 4G of physical
|
|
|
|
memory. All the memory that can't be mapped directly will be treated
|
|
|
|
as high memory.

However, this it experimental on 32-bit architectures, so if unsure say
|
|
|
|
N (on x86-64 it's automatically enabled, instead, as it's safe there).
