Interrupts and Exceptions CPU Modes and Address Spaces Dual-Mode Of
CPU Modes and Address Spaces There are two processor (CPU) modes of operation: • Kernel (Supervisor) Mode and • User Mode The processor is in Kernel Mode when CPU mode bit in Status Interrupts and Exceptions register is set to zero. The processor enters Kernel Mode at power-up, or as result of an interrupt, exception, or error. The processor leaves Kernel Mode and enters User Mode when the CPU mode bit is set to one (by some instruction). Memory address space is divided in two ranges (simplified): • User address space – addresses in the range [0 – 7FFFFFFF16] Studying Assignment: A.7 • Kernel address space Reading Assignment: 3.1-3.2, A.10 – addresses in the range [8000000016 – FFFFFFFF16] g. babic Presentation B 28 g. babic 29 Dual-Mode of CPU Operation MIPS Privilege Instructions • CPU mode bit indicates the current CPU mode: 0 (=kernel) With CPU in User Mode, the program in execution has access or 1 (=user). only to the CPU and FPU registers, while when CPU operates • When an interrupt occurs, CPU hardware switches to the in Kernel Mode, the program has access to the full capabilities kernel mode. of processor including CP0 registers. • Switching to user mode (from kernel mode) done by setting CPU mode bit (by an instruction).

Bringing Virtualization to the X86 Architecture with the Original Vmware Workstation
12 Bringing Virtualization to the x86 Architecture with the Original VMware Workstation EDOUARD BUGNION, Stanford University SCOTT DEVINE, VMware Inc. MENDEL ROSENBLUM, Stanford University JEREMY SUGERMAN, Talaria Technologies, Inc. EDWARD Y. WANG, Cumulus Networks, Inc. This article describes the historical context, technical challenges, and main implementation techniques used by VMware Workstation to bring virtualization to the x86 architecture in 1999. Although virtual machine monitors (VMMs) had been around for decades, they were traditionally designed as part of monolithic, single-vendor architectures with explicit support for virtualization. In contrast, the x86 architecture lacked virtualization support, and the industry around it had disaggregated into an ecosystem, with different ven- dors controlling the computers, CPUs, peripherals, operating systems, and applications, none of them asking for virtualization. We chose to build our solution independently of these vendors. As a result, VMware Workstation had to deal with new challenges associated with (i) the lack of virtual- ization support in the x86 architecture, (ii) the daunting complexity of the architecture itself, (iii) the need to support a broad combination of peripherals, and (iv) the need to offer a simple user experience within existing environments. These new challenges led us to a novel combination of well-known virtualization techniques, techniques from other domains, and new techniques. VMware Workstation combined a hosted architecture with a VMM. The hosted architecture enabled a simple user experience and offered broad hardware compatibility. Rather than exposing I/O diversity to the virtual machines, VMware Workstation also relied on software emulation of I/O devices. The VMM combined a trap-and-emulate direct execution engine with a system-level dynamic binary translator to ef- ficiently virtualize the x86 architecture and support most commodity operating systems. -

Efficiently Protecting Virtualized Desktop Infrastructures Against
Efficiently Protecting Virtualized Desktop Infrastructures Against Malware Performance Comparison between Traditional- and Centralized Antivirus Arris Huijgen University of Twente Graduation Committee University of Twente Dr. Pascal van Eck Radboud University Nijmegen Dr.ir. Erik Poll Deloitte Coen Steenbeek, MSc Henri Hambartsumyan, MSc June 18, 2013 Executive Summary The cloud is getting increasingly popular and also desktops are migrated to the cloud which are called Hosted Virtual Desktops (HVDs). Because virtualization makes hard- ware resources very flexible, it is often used to build a cloud platform. These desktops also need to be protected against malware. Virtualization software provider VMware added capabilities to its corporate product to provide antivirus protection from outside the Virtual Machine (VM) using its vShield module. Several antivirus vendors including Trend Micro developed antivirus software making use of this module. Because no comparisons have been done yet between traditional antivirus and antivirus software making making use of virtualization, research has been conducted compar- ing Trend Micro's traditional antivirus software Worry-Free Business Security (WFBS) with its vShield-compatible antivirus software called Deep Security (DS). This research showed that despite self-protection measures it is relatively easy to disable or remove the DS antivirus software inside the HVD without being detected. Moreover, it turned out that in this small environment simulating 10 HVDs, the performance of WFBS is much better compared to DS while DS also used much more resources. This is a remark- able result as DS is specifically aimed for virtualized environments and can therefore be expected to perform better than the traditional WFBS antivirus software.
