Abstract
Methods, apparatus, systems and articles of manufacture to control address space isolation in a virtual machine are disclosed. An example apparatus includes an address width adjustor to identify a memory width value corresponding to a guest memory associated with a virtual machine (VM), and generate an expanded emulated memory width value. The example apparatus also includes a memory mirror manager to generate a first guest physical address (GPA) range based on the memory width value, and generate a second GPA range based on the expanded emulated memory width value. The example apparatus also includes an EPT generator to generate root paging structures of a first type of EPT with respective addresses within the first GPA range, and generate root paging structures of a second type of EPT with respective addresses within (a) the first GPA range and (b) the second GPA range.
