The hypervisor includes a setting item information holding unit that holds setting item information in which a security policy is indicated by the setting value of a setting item; a setting detecting unit that monitors an instruction executed by the guest OS and the output of the physical device to detect the setting value that is set in the setting item of the setting item information holding unit or a setting value that is about to be changed therein; and a setting applying unit that, when the detected setting value and the setting value indicated by the setting item information differ from each other, applies the setting value indicated by the setting item information to the guest OS or application that is the setting target of the setting item."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Virtual machine system, system for forcing policy, method for forcing policy, and virtual machine control program","description":"A virtual machine system that builds one or more virtual machines on a real machine has a hypervisor for realizing access to virtualized hardware by a guest OS that is an operating system running on t","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8468522","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.
