In cloud computing, efficiencies are reaped by resource sharing such as co-location of computation and deduplication of data. This work exploits resource sharing in virtualization software to build a powerful cache-based attack on AES. We demonstrate the vulnerability by mounting Cross-VM Flush+Reload cache attacks in VMware VMs to recover the keys of an AES implementation of OpenSSL 1.0.1 runn...

Executive Summary Virtualization has become one of the hottest technologies in recent years. With the continuous growth of processing power and the increasing number of processor cores in servers, virtualization has become very attractive for many companies. As more and more IBM® InfoSphere® Information Server customers begin to adopt virtualization technology, understanding the performance cha...

Virtualization started to gain traction in the domain of information technology in the early 2000’s when managing resource distribution was becoming an uphill task for developers. As a result, tools like VMWare, Hyper-V (hypervisor) started making inroads into the software repository on different operating systems. VMWare and Hyper-V could support multiple virtual machines running on them with ...

ESX Server 2 provides memory access optimization for both Intel processors and AMD Opteron processors in server architectures that support NUMA (nonuniform memory access). This white paper provides background on NUMA technologies and a detailed description of the sophisticated NUMA optimizations available in ESX Server 2. The document contains the following sections: • Introduction • What is NU...

As the emergence of the Information Era continues, courses in information technology have been in high demand in educational institutions nationwide. In the Spring 2001 semester, at Purdue University, a new undergraduate course designed for non-networking majors concentrating on the exploration of network protocols, network operating system fundamentals, network operating systems, and directory...

VMware ESX Server 3.5 is designed for high performance. With a number of optimizations for superior performance, even the most I/O‐intensive applications perform well when deployed on VMware Infrastructure 3. In this paper we compare the performance of a virtual machine to that of a similarly configured native machine using the industry standard SPECweb2005 workload. In our virtualized tests we...
