BACKGROUND A Virtual Machine (VM) is an efficient, isolated duplicate of a real computer system. More than one VM may be provided concurrently by a single real system. A real system may have a number of resources that it provides to an operating syst…

BACKGROUND INFORMATION An embodiment of the present invention relates generally to virtualization platforms and, more specifically, to a system and method to run components of a virtual machine monitor at a reduced privilege level. Various mechanisms…

BACKGROUND As recognized in Revision 2.0 of the Intel® Virtualization Technology Specification for the Intel® Itanium® Architecture (VT-I), dated April 2005 (hereinafter "the VT-I Specification"), conventional operating system (OS) designs typic…

BACKGROUND OF THE INVENTION The present invention relates to virtual machine implementations, and in particular to a safe general purpose virtual machine that generates optimized virtual machine computer programs that are executable in a general purp…

BACKGROUND INFORMATION Various mechanisms exist for managing memory in a virtual machine environment. A virtual machine platform typically executes an underlying layer of software called a virtual machine monitor (VMM) which hosts one to many operati…

BACKGROUND OF THE INVENTION The invention generally relates to virtual machine management, and more particularly to efficient scheduling of virtual machines using processor state information. Virtualization of machine resources has been of significan…

BACKGROUND This invention relates to virtual machines. In particular, the invention relates to translation lookaside buffers that support a virtual-machine system. A virtual-machine system is a computer system that includes a virtual machine monitor…

BACKGROUND Computer viruses are a common problem for computer users. One typical mode of attack is to send an electronic mail message (e-mail) containing a file attachment to an unsuspecting user's computer. The file attachment contains malicious att…

BACKGROUND OF THE INVENTION A conventional virtual-machine monitor (VMM) typically runs on a computer and presents to other software the abstraction of one or more virtual machines. Each virtual machine may function as a self-contained platform, runn…

BACKGROUND The present disclosure relates generally to microprocessor systems, and more specifically to microprocessor systems that may operate in a trusted or secured environment. Processors may operate in several processor operating modes depending…
