Abstract
This disclosure generally relates to hypervisor memory virtualization. In an example, multiple page table stages may be used to provide a page table that may be used by a processor when processing a workload for a nested virtual machine. An intermediate (e.g., nested) hypervisor may request an additional page table stage from a parent hypervisor, which may be used to virtualize memory for one or more nested virtual machines managed by the intermediate hypervisor. Accordingly, a processor may use the additional page table stages to ultimately translate a virtual memory address for a nested virtual machine to a physical memory address.
