چکیده
Question 1.�� System Virtualization A hot new topic in operating systems is system virtualization. While IBM has been offering its VM system for mainframes for many years, virtualization technologies are now migrating to PC architectures, including PowerPCand i86-based chips. A second trend is the development of multi-core machines, where a single chip essentially implements a small-scale multiprocessor machine. The result will be that multiple virtual machines (and their guest operating systems) can concurrently run on a single chip.

متن کاملSecurity Implications of Different Virtualization Approaches for Secure Cyber Architectures
Virtualization is increasingly being used as a component in designing secure cyber architectures. The proposed applications include strong isolation, monitoring, fault tolerance, execution replay, etc. However, there are various virtualization approaches which differ in their security implications, proper applications, overheads, requirements, and most importantly threat models. Firstly, virtua...
متن کاملIntel Virtualization Technology: Hardware Support for Efficient Processor Virtualization
Virtualizing the physical resources of a computing system to improve sharing and utilization has been done for decades. Virtualization had once been confined to specialized server and mainframe systems, but improvements in the performance of platforms based on Intel technology now allow those platforms to efficiently support virtualization. However, the IA-32 and Itanium processor architectures...
