Guest VMs execute within a protected region of memory (called a key domain) that even the host VMM cannot access. Virtualization data structures that pertain to the execution state (e.g., a Virtual Machine Control Structure (VMCS)) and memory mappings (e.g., Extended Page Tables (EPTs)) of the guest VM are also located in the protected memory region and are also encrypted with the key domain key. The host VMM and other guest VMs, which do not possess the key domain key for other key domains, cannot directly modify these control structures nor access the protected memory region. The host VMM, however, using VMPageIn and VMPageOut instructions, can build virtual machines in key domains and page VM pages in and out of key domains."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Secure public cloud using extended paging and memory integrity","description":"A host Virtual Machine Monitor (VMM) operates “blindly,” without the host VMM having the ability to access data within a guest virtual machine (VM) or the ability to access directly control structures","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11520611","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.
