SYSTEMS, METHODS AND COMPUTER PROGRAM PRODUCTS FOR BOOTSTRAPPING A TYPE 1 VIRTUAL MACHINE MONITOR AFTER OPERATING SYSTEM LAUNCH

摘要

Systems, methods, and computer program products that provide for the use of a type 2 VMM to de-link or isolate underlying processor hardware from an operating system. This may allow the launching of a task that requires direct access to processor hardware, where such access requires the absence of an operating system. Such a task may take the form of a type 1 VMM, such as an information security or integrity VMM, e.g., an anti-malware VMM.

1. A method, comprising:
given an operating system (OS) running on a processor, running a type 2 virtual machine monitor (VMM) that isolates the OS from the processor; and launching a task that requires access to the processor in isolation from the
