The system may include a translation look-aside buffer (TLB) to maintain a policy to lock one or more guest linear addresses (GLAs) to one or more allowable guest physical addresses (GPAs); a page walk processor to update the TLB based on the guest page tables; and a page table edit control (PTEC) module to: identify entries of the guest page tables that map GLAs associated with the policy to a first GPA; verify that the mapping conforms to the policy; and place the guest page table into one of a plurality of restricted accessibility states based on the verification, the restricted accessibility applied to the VM guests and to the page walk processor."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Dynamic page table edit control","description":"Generally, this disclosure provides systems, methods and computer readable media for a page table edit controller configured to control access to guest page tables by virtual machine (VM) guest softwa","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9710393","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
