▼ Contemporary organizations have access to a swiftly expanding selection of computing, storage and networking technologies. A remarkable trend of the past decennium is the advent of
virtualization technologies. In this period, many IT companies shifted their attention to
virtualization. This has led to the development of many types of
virtualization technologies. In this report, a taxonomy model has been made in which
virtualization technologies have been structured. In the taxonomy model, a virtual server architecture is displayed, showing the various layers of hardware, software and their relation with the
virtualization domains. A case study was conducted with well-known
virtualization vendors to evaluate the taxonomy model and at the same time identify the main
virtualization trends.

▼ Modern
virtualization systems must balance fair access to I/O resources while still maintaining high utilization of those resources. It is difficult to balance fairness and efficiency when scheduling disk accesses due to the non-uniform nature of disk I/O. Current open source
virtualization systems, including Xen and KVM, utilize the stock Linux disk scheduler to provide access to storage. Although the Linux disk scheduler can provide good I/O performance for individual virtual machines, it does not necessarily provide equal access to disk I/O resources across competing virtual machines. This can result in unfair and unpredictable application I/O performance behavior among virtual machines.
This thesis presents the Virtual Deadline I/O Scheduler, a new disk scheduler that improves the fairness of scheduling I/O resources across virtual machines. The virtual deadline scheduler makes the Linux deadline I/O scheduler
virtualization-aware, enabling it to schedule I/O requests more adaptively and fairly. In particular, request deadlines are dynamically determined based upon the level of service that has been provided to the vir- tual machine from which the request originated. The virtual deadline scheduler increases fairness of I/O performance while minimizing aggregate performance degradation.

▼ Server
virtualization is the partitioning of a physical server into smaller virtual servers to maximize your server resources. In server
virtualization, the resources of the server itself are hidden, or masked from users and the software is used to divide the physical server into multiple virtual environments, called virtual or private servers. This is in contrast to dedicate one server to a single application or task. This technology brings positive transformations such as reduced hardware costs, improved server provisioning and deployment, better disaster recovery solutions, efficient and economic use of energy, and increased staff productivity to companies that adopt it.
Industry will continue to adopt
virtualization for many reasons: collections of inefficient servers can be replaced with fewer machines; software can be tested while isolated in harmless virtual partitions; and data centers can gracefully (and virtually) conform to shifting work models, new technologies and changing corporate priorities.
The future of enterprise IT management will be based on virtual computing.

▼ Distributed applications often require complex trust
relationships between remote parties in order to enable a wide
range of complex functionality. Unfortunately, it is
difficult to achieve useful guarantees when interacting
with remote systems in the face of an attacker with physical
access. Specifically, we need a solution that is both
comprehensive and usable for a wide variety of trustworthy
distributed applications. This thesis presents such a solution,
comprised of two main parts: a secure trusted computing base
(sCore) using secure hardware on which applications run in virtual
machines and a control infrastructure to manage the virtual
machines (TVMI). We use virtualization to separate programs and
trusted computing to verify the software stack on which they run.
This enables us securely form groups of applications which utilize
the separation and trust established by the sCore. In order to do
this, we build a secure core of software (sCore), which establish
mutual trust with each other to build a distributed reference
monitor with strong security guarantees. Using this trustworthy
platform, we create an infrastructure for managing coalitions of
virtual machines. This enables groups of applications capable of
entering well-founded trust relationships with each other. We then
use formal verification to prove relevant security
properties of the virtual machine control infrastructure which runs
on the trusted computing base. We build our sCore and TVMI in order
to demonstrate that our solutions are feasible in a realistic
setting, deliver acceptable performance, and provide security
properties that were not previously available. Additionally, our
formal verification demonstrates that the critical
properties the TVMI purports to enforce are met by our design. This
helps to demonstrate the important problems in distributed, secure
virtualization that are not being handled today, and gives a
framework for their evaluation and operation.

▼ Cloud computing is a new concept that incorporates many existing technologies, such as
virtualization.
Virtualization is important for the establishment of cloud computing. With
virtualization, cloud computing can virtualize the hardware resources into a huge resource pool for users to utilize. This thesis begins with an introduction to how a widely used service model classifies cloud computing into three layers. From the bottom up, they are IaaS, PaaS, and SaaS. Some service provides are taken as examples for each service model, such as Amazon
Beanstalk and Google App Engine for PaaS; Amazon CloudFormation and Microsoft mCloud for IaaS. Next, we turn our discussion to the hypervisors and the technologies for virtualizing hardware resources, such as CPUs, memory, and devices. Then, storage and network
virtualization techniques are discussed. Finally, the conclusions and the future directions of
virtualization are drawn.

▼ In most of today's operating system architectures, device drivers are tightly coupled with other kernel components. In such systems, a fault caused by a malicious or faulty device driver often leads to complete system failure, thereby reducing the overall reliability of the system. Even though a majority of the operating systems provide protection mechanisms at the user level, they do not provide the same level of protection for kernel components. Using
virtualization, device drivers can be executed in separate, isolated virtual machines, called driver domains. Such domains provide the same level of isolation to device drivers as operating systems provide to user level applications. Domain-based isolation has the advantage that it is compatible with existing drivers and transparent to the kernel.
However, domain-based isolation incurs significant performance overhead due to the necessary interdomain communication. This thesis investigates techniques for reducing this overhead. The key idea is to replace the interrupt-based notification between domains with a spinning-based approach, thus trading CPU capacity for increased throughput.
We implemented a prototype, called the Isolated Device Driver system (IDDR), which includes front-end and back-end drivers and a communication module. We evaluated the impact of our optimizations for a variety of block devices. Our results show that our solution matches or outperforms Xen's isolated driver domain in most scenarios we considered.

▼ Unikernels are lightweight, single-purpose virtual machines designed for the cloud. They provide enhanced security, minimal resource utilisation, fast boot times, and the ability to optimize performance for the target application. Despite their numerous advantages, unikernels face significant barriers to their widespread adoption. We identify two such obstacles as unscalable boot procedures in hypervisors and the difficulty in porting native applications to unikernel models. This work presents a solution for the first based on the popular Xen hypervisor, and demonstrates a significant performance benefit when running a large number of guest VMs. The HermiTux unikernel aims to overcome the second obstacle by providing the ability to run unmodified binaries as unikernels. This work adds to HermiTux, enabling it to retain some of the important advantages of unikernels such as fast system calls and modularity.

▼ Virtualization has become a very popular research topic in recent years.
Virtualization is used in varied applications such as e-Learning, business-to-business communication, social networking, computer simulation and enterprise development. These advances are due to the availability of high-speed computers, fiber-optic-enabled internet connections and advanced
virtualization programs. However, only a very small amount of research has been conducted, most especially on the performance of
virtualization programs. Thus little is known about the performance of the various
virtualization programs such as VMware Workstation and VirtualBox. When dealing with
virtualization, performance is of primary importance. This thesis reports on the performance of different
virtualization programs, such as VMware Workstation 7 and Oracle VM VirtualBox 4 using MS Windows 7 guest-and host-operating systems. The chosen research methodology for this research is a mixed research methodology based on both qualitative and quantitative. A mixed research methodology allows the researcher to easily collect primary data via qualitative methods and then analyze the data using quantitative methods. The main purpose of this study is to find any performance differences in between VMware Workstation and VirtualBox based on Windows 7 guest and host OSs. Various experiments were conducted regarding the performance of VMware Workstation, VirtualBox and Microsoft Windows Virtual PC using Windows 7 and Linux Mint guest OSs and Windows 7 host OS. Findings of the experiments revealed that there are performance differences among VMware Workstation, VirtualBox and Virtual PC. In
virtualization, it is generally thought that VMware Workstation is superior to other
virtualization programs. However empirical results obtained from this study show that the performance of VMware Workstation and VirtualBox are similar. VMware Workstation has many features but its performance is not very different from VirtualBox. Virtual PC on the other hand is not a reliable product for serious
virtualization as it lacks features, performance and support for different host and guest OSs. The overall findings of this study show that VMware Workstation and VirtualBox both meet performance and feature requirements for creating reliable virtual environments. This study opens a new path for research in the area related to performance of
virtualization programs. Data gathered from this study was used to make meaningful conclusions in Chapter 6. The conclusion explores possible directions for future research on the performance of
virtualization programs. Findings of this study may help businesses to select appropriate
virtualization program as part of their information technology infrastructure and thereby benefit from using
virtualization technology.

▼ The requirement of high quality services is increasing day by day. So, in order to meet up with this requirement new technologies are being developed one of them being virtualization. The main agenda of introducing virtualization is that though virtualization needs more powerful devices to run the hypervisor, the technique also helps to increase consolidation which makes efficient use of resources like increase in the CPU utilization. The virtualization technique helps us to run more VM’s (Virtual Machine) on the same platform i.e. on the same hypervisor. In virtualization as number of VM’s share the CPU will there be any effect on the performance of TCP with the performance influencing factors of virtualization. While TCP being the most widely used protocol and most reliable protocol can performance of TCP vary if different TCP congestion control mechanism are used in the virtualized environment are the main aims of this research. In this study, we investigate the performance influencing factor of TCP in the virtualized environment and whether those influencing factors have any role to play with the performance of the TCP. Also which TCP congestion control mechanism is best suitable in order to download files when virtualization is used will be investigated by setting up a client-server test bed. The different TCP congestion control mechanism which have been used are CUBIC, BIC, Highspeed, Vegas, Veno, Yeah, Westwood, LP, Scalable, Reno, Hybla. Total download time has been compared in order to know which congestion control algorithm performs better in the virtualized environment. The method that has been used to carry out the research is by experimentation. That is by changing the RAM sizes and CPU cores which are the performance influencing factors in virtualization and then analyzing the total download time while downloading a file by changing the TCP congestion control mechanisms by running a single guest VM. Apart from changing only congestion control mechanisms the other network parameters which effect the performance of the TCP such as Delay have been injected while downloading the file, to match up with the real time scenarios. Results collected include average download time of a file by changing the different memory sizes and different CPU cores. Average Download time for different TCP congestion controls mechanisms with inclusion of the parameter that effects the total download time such as Delay. From the results we got we can see that there is a slight influence on the performance of TCP by the performance influencing factors memory sizes and CPU cores allotted to the VM in the KVM virtualized environment and of all the TCP congestion control algorithms having TCP – BIC and TCP- YEAH performs the best in the KVM virtualized environment. The performance of TCP – LP is the least in the KVM virtualized environment.

▼ Trusted Computing is a relatively new approach to computer security in which a system should be permanently maintained in a well-defined state - and therefore it will reside in a trustworthy state. The word "trustworthy" in this context means that the system always behaves in a specific
way as defined by the platform manufacturer and/or the administrator/owner. A key element
of this approach is to employ a security module, which is implemented in hardware, and which is tied to the platform so as to serve as a trust anchor. Based on that ’root of trust’ and other features, an effective security architecture is proposed in this research.
Virtualization techniques, which were formerly developed for server consolidation, cost reduction, and conservation of energy are now gaining more and more interest in the field of trusted computing.
Virtualization can greatly enhance the security of a system by isolating
applications, or even whole operating systems, by splitting the computer system into smaller parts, whose integrity can be more easily assured.
This project is concerned with the development of a system that will effectively combine the isolation features of the
virtualization schemes with a state-of-the-art hardware security module. This system will provide reliable protection against sophisticated software-based
attacks and will withstand elementary hardware-based attacks. The building block approach of this proposed security architecture makes sure that many different application fields can archive a high level of security by combining the appropriate components.
The research examines some emerging approaches to computer security and proposes a novel security architecture based on a hardware trust anchor. An experimental system is developed to provide a ’proof-of-concept’ model for evaluation. The target application area for the architecture is the embedded computing space, in particular x86 based architectures. The selection of hardware elements and the choice of hypervisor are discussed and justified. The
assumptions on the features of the architecture are evaluated and validated in the context of potential security improvements. Future research in this niche area is proposed.

▼ Virtual machines (VMs) are useful mechanisms for
better resource utilization, support for special software
configurations, and the movement of packaged software across
systems. Exploiting VM advantages in a production setting, however,
often requires computer systems with the smallest possible
disk-size footprint. Administrators and programmers who create VMs,
however, may need a robust set of tools for development. This
introduces an important conflict: Minimalism demands that packaged
software be as small as possible, while completeness demands that
nothing required is missing. We present a system called Lilliputia,
which combines resource usage monitoring (through a Linux FUSE
filesystem we created called StatFS), with a filtered cloning
system, which copies an existing physical or virtual machine into a
smaller clone. Finally, we show how Lilliputia can reduce the size
of the Trellis Network-Attached-Storage (NAS) Bridge Appliance and
the Chemical Shift to 3D Structure protein structure predictor to
10-30% of their original size.

▼ Virtual machine environments are becoming more common
due to the increased performance of commodity hardware and the
emergence of cloud computing for large scale applications. As the
use of virtual machines continues to grow, performance critical
applications will require efficient mechanisms to achieve their
tasks. We introduce Nahanni as a mechanism for shared memory
communication in virtual machine environments. Nahanni allows
virtualized applications, those running inside virtual machines, to
communicate through shared memory for both data movement and
synchronization when VMs are co-located on the same host machine.
We describe the design, implementation, and evaluation of Nahanni
as part of the QEMU/KVM virtualization platform. We have modified
existing communication layers to measure the performance benefit of
Nahanni. Through microbenchmarks and applications, we demonstrate
that shared memory is a useful and efficient communication
mechanism in virtualized environments. Further, we discuss how the
design and implementation of Nahanni enables a new class of
applications, ones that use structured data, to benefit from the
use of shared memory.

▼ Virtualization is one of the cornerstone technologies that makes utility computing platforms such as cloud computing a reality. With the accelerating adoption of cloud computing, the virtualizaion-based cloud platforms are consuming a significant amount of energy. However, the design of a green and efficient virtualization technology remains an open issue to both industry and academia. In this thesis, we for the first time investigate the virtual machine's (VM's) power consumption while supporting different services and applications (e.g., web, database and streaming). In particular, we establish a cloud computing platform in the The University of Minnesota Duluth. This platform consist of both Xen and KVM nodes and the VMs can be easily accessed from the Internet. Our real-world measurement indicates that the existing virtulization technologies add considerable energy overhead to the data centers. For example, a busy virtualized database server can consume 30% more energy than its non-virtualized counterparts. To address such a problem, we propose a shared-memory-based enhancement to reduces the extra interrupts and memory copies for cloud virtualization. The evaluation indicates that our approach can reduce VM's energy consumption by 11% without noticeable loss of its running performance.

▼ An intrusion prevention system is a variation of an intrusion detection system that drops packets that are anomalous based on a chosen criteria. An intrusion prevention system is typically placed on the outer perimeter of a network to prevent intruders from reaching vulnerable machines inside the network, though it can also be placed inside the network in front of systems requiring extra security measures. Unfortunately, intrusion prevention systems, even when properly configured, are susceptible to both false positives and false-negatives. The risk of false positives typically leads organizations to deploy these systems with the prevention capability disabled and only focus on detection. In this paper I propose an expansion to current intrusion prevention systems that combines them with the principles behind honeypots to reduce false positives while capturing attack traffic to improve prevention rules. In an experiment using the Snort-inline intrusion prevention system, I was able to reduce the rate of false positives to zero without negatively impacting the rate of false-negatives. I was further able to capture a successful attack in a way that minimized disruption to legitimate users but allowed the compromised system to be later analyzed to find weaknesses, improve prevention rules, and prevent future attacks.

▼ The Integrity Measurements Architecture (IMA) provides attestation and integrity for Linux hosts. But what if an administrator wants to provide IMA functionality to an older (non-IMA capable) or a non Linux-based OS? If the system is deployed on top of a hypervisor, IMA functionality can be provided at the hypervisor level. This paper applies Virtual Machine Introspection (VMI) to provide IMA functionality to virtualized guest OSes. We implement a proof of concept library (using a shallow shadow filesystem) and integrate it with the Kernel-based Virtual Machine (KVM) hypervisor. The modifications provide the Linux host OS the ability to see when and what files are being accessed by the guest OS. This paper outlines the approach to its design, concept of execution, and describes the challenges encountered. The library is tested with a sample bash script created in a monitored partition; a hash of the file is printed before the file is loaded into memory.

▼ We presents dfork, a new abstraction for performance and security isolation of processes. Whereas the normal fork system call provides a private address space for a child process, dfork leverages
virtualization and other techniques to also provide a separate kernel and file system container. Further, unlike many existing
virtualization-based approaches, dfork can be used recursively with no cumulative performance penalty, so an isolated process can itself spawn further isolated subprocesses. In contrast to existing software sandbox approaches, our system does not require an a priori policy in order to provide strong security guarantees. Finally, we show that the dfork approach is hypervisor agnostic – our implementation works under both the bare-metal Xen hypervisor and the OS-hosted VMware Workstation hypervisor.
We have implemented the dfork model under Linux in a system we call Isolar. This implementation creates Xen or VMware domains that are NFS booted from a union file system. The end result is an environment that can isolate the effects of malicious activity up to and including a complete takeover of the guest kernel, including kernel-level rootkits. Further, the user may elect to selectively commit changes to the underlying file system, accepting some changes, keeping some isolated, and discarding others entirely. This is especially useful in understanding and reverting changes made by an isolated kernel-level rootkit. This thesis discusses the dfork architecture, provides an example implementation, presents a quantitative analysis of the security and performance isolation provided, and gauges the performance impact of the implementation as a whole.

▼ Mestrado em Engenharia Informática
In an era marked by the so-called technological revolution, where computing power has become a critical production factor, just like manpower was in the industrial revolution, very quickly this dispersal of computing power for numerous facilities and sites became unsustainable, both economically as well in terms of maintenance and management. This constringency led to the need of adopting new strategies for the provision of information systems equally capable but in a more consolidated way, while also increasing the desired levels of the classic set of information assurances: availability, confidentiality, authenticity and integrity. At this point enters a topic not as new as it may seem, virtualization, which after two decades of oblivion presents itself as the best candidate to solve the problem technology faces today. Throughout this thesis, it will be explained what this technology represents and what approach should be taken in the evolution of a systems architecture classical model into a model based in optimization, high availability, redundancy and consolidation of information communications and technology, using networks and systems virtualization. A number of good management principles to adopt will also be taken into account to ensure quality standards in providing services, culminating in a practical application of this model to the infrastructure of the company Metro do Porto, SA. Briefly, this document can almost be classified as a step by step manual for the understanding and implementation of this model, transversal to any infrastructure without extremely particular needs or constraints which derail conversion.
Numa era marcada pela chamada revolução tecnológica, em que o poder de computação se tornou um factor crítico de produção, tal como a mão-de-obra o foi na revolução industrial, rapidamente esta dispersão do poder de computação por inúmeros equipamentos e locais tornou-se insustentável, quer ao nível económico como de manutenção e gestão.
Este constrangimento levou à necessidade de adopção de novas estratégias para a disponibilização de sistemas de informação igualmente capazes mas de forma mais consolidada, procurando simultaneamente aumentar os níveis desejáveis do clássico paradigma dos factores a garantir na informação: disponibilidade, confidencialidade, autenticidade e integridade. É neste ponto que entra um tema não tão novo como parece, a virtualização, que após duas décadas de esquecimento se apresenta como o maior candidato à resolução do problema que a tecnologia enfrenta. Ao longo desta tese, será explicado o que esta tecnologia representa e qual a abordagem a ter na evolução de um modelo clássico de arquitectura de sistemas para um modelo baseado em optimização, alta disponibilidade, redundância e consolidação de tecnologias de informação e comunicações com recurso à virtualização de redes e sistemas. Serão igualmente tidos em conta um número de bons princípios de gestão a adoptar de forma a garantir parâmetros de qualidade na…

▼ Truck Data Warehouse (TDW) System is a web-based application developed at the California State University Sacramento for the California Department of Transportation (Caltrans). The TDW System allows Caltrans to use this web-based application system to generate online reports on various statistics related to truck data that passes through the different weigh stations across California.
The current prototype system of TDW was developed using Oracle 10g database and SUSE Linux 9.0 as the operating system. It also uses Oracle Business Intelligence (BI) tools such as Oracle Discoverer Plus to generate the BI reports. Moreover, this application uses Google Maps API and JSP to locate the weight station on the map. SQL loader utility was used for loading ASCII files in a very specific format to populate the database.
In this project, the existing prototype application is being recreated in a virtualized environment by using VMware ESXi 4.0 Update 1 as the
virtualization software and Oracle Enterprise Linux 4.0 as the operating system. Oracle 10g Release 2
v
and MySQL-server-5.1.45-1 databases are setup to compare the execution time analyze the efficiency and behavior of these databases in a virtualized environment. The described scenario is being created on a single physical machine where execution times of the pre-defined reports in these two environments are compared and analyzed.

▼ Cette thèse vise à interroger la situation de l'individu face à l'horizon virtuel de l'ère interconnectée, ainsi que la créativité surgie du cyberespace. Divisée en deux parties, la première section de cette thèse consiste en une analyse des expériences plastiques, elles-mêmes élaborées en rapport avec les réseaux sous diverses formes : installation, net-art, vidéo, photographie numérique et performance GPS. Les quatre projets artistiques proposés ont ainsi permis une interrogation sur la question du regard, qui, dans le cadre des arts plastiques, traverse à la fois l'auteur, le dispositif et le spectateur. Dans la seconde section,il s'agit de tenter de répondre davantage aux problématiques engagées par ces expériences artistiques. La métaphore du « cycle hydrologique » est d'abord proposée afin de comprendre les réseaux informatiques. Une approche du devenir de l'image du monde est ensuite réalisée à travers un parcours historique sur des cartes géographiques. L'hypothèse proposée est que si ce parcours et cette évolution sont conçus comme la transformation d'une conception mythologique du monde en une représentation rationnelle, l'imaginaire engagé par les cartes numériques peut impliquer à nouveau certaines caractéristiques d'une représentation mythologique. Des phénomènes culturels se trouvant à la frontière du cybermonde sont analysés, dans lesquels les questions du virtuel s'avèrent déterminantes, en particulier celle de la réalité augmentée, de la durée d'immersion virtuelle, de « l'auto-virtualisation » et rejoignent à nouveau l'hypothèse d'une mythologie propre à l'espace-temps virtuel édifié sur les réseaux.
This thesis aims to examine the situation of individuals facing virtual space in the interconnected era and the creativity that emerges in the cyberspace. The thesis is divides into two parts. The first part consists of an analysis of my personal experience in conducting four art projects elaborated in various forms, including installation art, net.art, video art, digital photography and GPS performance art. Regardless of which artistic form is in question, « look » is the key in connecting the author, the audience as well as the visual media. The second part aims to further explore the artistic issues derivated from the personal experience, namely net art, map and virtuality. In order to fulfil this task, the metaphor of « water cycle » is applied to conceptualize the development of internet in a systematic way. In addition, world maps at different stages of human civilization are analyzed to shed light on how the worlview has changed over time. Based on that, a hypothesis is proposed : if the changes in world maps over the course of human history reflects a gradual replacement of a mythological perception of the world by a more rational perspective, the creativity shown in trendy digital maps nowadays might point to a resuscitation of a world view featuring mythological representation. Some cultural phenomena in the cyber space are also analyzed. The focus of the analysis is on a few issues related…

▼ Cloud computing has emerged as an economically attractive utility model for computational resources. An increasing number of industries, from businesses to governments, are embracing cloud computing. However, the economic benefits of the cloud computing model come at a price: the loss of control over how services and applications can use computing resources. In other words, cloud computing is fundamentally provider-centric. Cloud providers (the providers of computational resources), not cloud users (the consumers of computational resources), dictate rules and policies governing how computational resources can be used. For large enterprise application workloads, adhering to cloud provider rules and policies may be prohibitive. This dissertation explores the question: how can large enterprise workloads efficiently utilize and control computational resources from a variety of providers in the cloud computing model? The main contributions of this dissertation relate to a fundamental change to the cloud computing model. Instead of a provider-centric model, we propose a user-centric model in which the cloud user can maintain control over how computational resources obtained from cloud providers can be used. We have devised a new abstraction, called cloud extensibility, to enable the implementation of provider-level functionality by cloud users. Leveraging cloud extensibility, we describe steps towards a user-centric cloud computing model that grants cloud users-including large enterprises-control over resources obtained from one or more cloud providers. We call this new model the supercloud model. More specifically, we focus on three key areas in which current providercentric cloud computing models do not expose the necessary control or lack the features to support large enterprise workloads without significant reconfiguration effort. First, clouds are not interoperable, restricting workloads to a single provider and hindering incremental migration to the cloud. Second, clouds lack support for complex enterprise network configurations, including flow policies between application components and low-level network features (e.g., IP addresses, multicast, VLANs). Finally, high utilization of cloud resources cannot be applied through techniques like oversubscription, and existing techniques do not apply well to common workload patterns. We subsequently make three contributions, embodied in the design, implementation and evaluation of three systems that leverage cloud extensibility. Cloud extensibility itself is instantiated in the first system, a nested
virtualization layer called the Xen-Blanket. The Xen-Blanket additionally enables cloud interoperability by homogenizing existing cloud interfaces and services. The second system, VirtualWire, provides a virtual network abstraction to support complex enterprise networks in which the cloud user manages the network control logic. Finally, we present Overdriver, a system that enables high resource utilization through memory oversubscription and the handling of the resulting-often…

▼ This study focuses on improving
virtualization performance by utilizing existing architectural infrastructures. The system encompasses the profiler that interacts with low-level architecture resources, a data collection module and a program that interprets this data. These components are used to quantify performance and co-schedule virtual machines to achieve optimum system performance. This thesis shows that by providing feedback to the hypervisor scheduler can improve individual virtual machine and overall system performance. Further studies will need to be done to further leverage this mechanism and develop various policies.

▼ Cloud services are currently being extensively used for server hosting, data storage, scientific and research purposes.
Virtualization technology is an essential element for these services.
Virtualization enables the creation of multiple virtual instances on physical or hardware infrastructure. Network
virtualization is a recent advancement in this field through which virtual networks can be created over real physical networks (also called as substrate networks). Such virtual networks facilitate testing and quick deployment of new technologies, better utilization of hardware and provide more flexibility to users.
A crucial element of network
virtualization is the stage in which the virtual networks are created on the substrate network. This process is of critical nature as the number of virtual networks that are created on the substrate are high. Hence the placement of these virtual networks needs to be done in a strategic way. The creation of virtual networks on a substrate network is referred to as Virtual network embedding. Determining the best way to place or create multiple virtual networks on a substrate network while satisfying a given set of constraints is referred to as Virtual network embedding problem. The technique or algorithms used to solve this problem are known as virtual network embedding algorithms.
In this thesis we evaluate and compare six virtual network embedding algorithms for embedding short-lived virtual networks on substrate networks with fat-tree topology and UUNET topology. We discuss different metrics to evaluate the performance of embedding algorithms and compare the algorithms based on these metrics. In particular, we examine the probability of success of embedding a virtual network, average substrate path length and the distribution pattern of virtual networks in the substrate network for six different algorithms. The aim of this thesis work is to compare the performance of virtual network embedding algorithms, observe the nuances of the approaches that contribute to optimal results and investigate the embedding for the case of short-lived virtual networks.

▼ Embedding of virtual network (VN) requests on top of a shared physical network poses an intriguing combination of theoretical and practical challenges. Two major problems with the state-of-the-art VN embedding algorithms are their indifference to the underlying substrate topology and their lack of re-optimization mechanisms for already embedded VN requests. We argue that topology-aware embedding together with re-optimization mechanisms can improve the performance of the previous VN embedding algorithms in terms of acceptance ratio and load balancing. The major contributions of this thesis are twofold: (1) we present a mechanism to differentiate among resources based on their importance in the substrate
topology, and (2) we propose a set of algorithms for re-optimizing and
re-embedding initially-rejected VN requests after fixing their bottleneck
requirements. Through extensive simulations, we show that not only our techniques improve the acceptance ratio, but they also provide the added benefit of balancing load better than previous proposals. The metrics we use to validate our techniques are improvement in acceptance ratio, revenue-cost ratio, incurred cost, and distribution of utilization.

▼ Graphics Processing Units (GPUs) are being adopted in many computing facilities given their extraordinary computing power, which makes it possible to accelerate many general purpose applications from different domains. However, GPUs also present several side effects, such as increased acquisition costs as well as larger space requirements. They also require more powerful energy supplies. Furthermore, GPUs still consume some amount of energy while idle and their utilization is usually low for most workloads.
In a similar way to virtual machines, the use of virtual GPUs may address the aforementioned concerns. In this regard, the remote GPU
virtualization mechanism allows an application being executed in a node of the cluster to transparently use the GPUs installed at other nodes. Moreover, this technique allows to share the GPUs present in the computing facility among the applications being executed in the cluster. In this way, several applications being executed in different (or the same) cluster nodes can share one or more GPUs located in other nodes of the cluster. Sharing GPUs should increase overall GPU utilization, thus reducing the negative impact of the side effects mentioned before. Reducing the total amount of GPUs installed in the cluster may also be possible.
In this dissertation we enhance one framework offering remote GPU
virtualization capabilities, referred to as rCUDA, for its use in high-performance clusters. While the initial prototype version of rCUDA demonstrated its functionality, it also revealed concerns with respect to usability, performance, and support for new GPU features, which prevented its used in production environments. These issues motivated this thesis, in which all the research is primarily conducted with the aim of turning rCUDA into a production-ready solution for eventually transferring it to industry. The new version of rCUDA resulting from this work presents a reduction of up to 35% in execution time of the applications analyzed with respect to the initial version. Compared to the use of local GPUs, the overhead of this new version of rCUDA is below 5% for the applications studied when using the latest high-performance computing networks available.; Las unidades de procesamiento gráfico (Graphics Processing Units, GPUs) están siendo utilizadas en muchas instalaciones de computación dada su extraordinaria capacidad de cálculo, la cual hace posible acelerar muchas aplicaciones de propósito general de diferentes dominios. Sin embargo, las GPUs también presentan algunas desventajas, como el aumento de los costos de adquisición, así como mayores requerimientos de espacio. Asimismo, también requieren un suministro de energía más potente. Además, las GPUs consumen una cierta cantidad de energía aún estando inactivas, y su utilización suele ser baja para la mayoría de las cargas de trabajo.
De manera similar a las máquinas virtuales, el uso de GPUs virtuales podría hacer frente a los inconvenientes mencionados. En este sentido, el mecanismo de virtualización remota de GPUs permite…

▼ Driven by Moore's Law, many computer architectures - ARM, x86, MIPS, PowerPC, SPARC - have evolved from 32-bit to 64-bit. To support existing applications, these have all kept support for a 32-bit compatibility mode. However, this comes at a cost in hardware complexity, power consumption and development time. Dynamic binary translation - recompiling binaries into the new instruction set at runtime - can be used instead of specific hardware for this purpose. While this approach has previously been used to assist architecture transition, these translators have all traded-off performance and transparency, a measure of how accurately they emulate the 32-bit environment. This thesis addresses ARM's transition from AArch32 to AArch64 through MAMBO-X64, a dynamic binary translator developed to support this transition. A range of novel optimizations were devised to improve translation performance while maintaining strict transparency. This follows a common theme of exploiting existing hardware features such as hardware return prediction, virtual memory and virtualization extensions to offset translation overheads. HyperMAMBO-X64 - a variant of MAMBO-X64 integrated in a hypervisor - was also developed to support system-level translation while remaining transparent to guest operating systems. Results demonstrate that the cost of binary translation is reduced, delivering performance competitive with the manufacturer's hardware. Performance in several benchmarks even exceeds that from the integrated compatibility mode. Thus MAMBO-X64 not only provides a means for architectural upgrade, but also an alternative to the expense of the legacy support currently employed.

▼ Successful realization of practical computer security improvements requires an understanding and insight into the system's security architecture, combined with a consideration of end-users' needs as well as the system's design tenets. In the case of Android, a system with an open, modular architecture that emphasizes usability and performance, acquiring this knowledge and insight can be particularly challenging for several reasons. In spite of Android's open source philosophy, the system is extremely large and complex, documentation and reference materials are scarce, and the code base is rapidly evolving with new features and fixes. To make matters worse, the vast majority of Android devices in use do not run the open source code, but rather proprietary versions that have been heavily customized by vendors for product differentiation.
Proposing security improvements or making customizations without sufficient insight into the system typically leads to less-practical, less-efficient, or even vulnerable results. Point solutions to specific problems risk leaving other similar problems in the distributed security architecture unsolved. Far-reaching general-purpose approaches may further complicate an already complex system, and force end-users to endure significant performance and usability degradations regardless of their specific security and privacy needs. In the case of vendor customization, uninformed changes can introduce access control inconsistencies and new vulnerabilities. Hence, the lack of methodologies and resources available for gaining insight about Android security is hindering the development of practical security solutions, sound vendor customizations, and end-user awareness of the proprietary devices they are using.
Addressing this deficiency is the
subject of this dissertation. New approaches for analyzing, evaluating and understanding Android access controls are introduced and used to create an interactive database for use by security researchers as well as system designers and end-user product evaluators. Case studies using the new techniques are described, with results uncovering problems in Android's multiuser framework and vendor-customized System Services. Finally, the new insights are used to develop and implement a novel
virtualization-based security architecture that protects sensitive resources while preserving Android's open architecture and expected levels of performance and usability.

▼ While one always works to prevent attacks and failures, they are inevitable and situational awareness is key to taking appropriate action. Monitoring plays an integral role in ensuring reliability and security of computing systems. Infrastructure as a Service (IaaS) clouds significantly lower the barrier for obtaining scalable computing resources and allow users to focus on what is important to them. Can a similar service be offered to provide on-demand reliability and security monitoring?
Cloud computing systems are typically built using virtual machines (VMs). VM monitoring takes advantage of this and uses the hypervisor that runs VMs for robust reliability and security monitoring. The hypervisor provides an environment that is isolated from failures and attacks inside customers’ VMs. Furthermore, as a low-level manager of computing resources, the hypervisor has full access to the infrastructure running above it. Hypervisor-based VM monitoring leverages that information to observe the VMs for failures and attacks. However, existing VM monitoring techniques fall short of “as-a-service” expectations because they require a priori VM modifications and require human interaction to obtain necessary information about the underlying guest system. The research presented in this dissertation closes those gaps by providing a flexible VM monitoring framework and automated analysis to support that framework.
We have developed and tested a dynamic VM monitoring framework called Hypervisor Probes (hprobes). The hprobe framework allows us to monitor the execution of both the guest OS and applications from the hypervisor. To supplement this monitoring framework, we use dynamic analysis techniques to investigate the relationship between hardware events visible to the hyper-visor and OS constructs common across OS versions. We use the results of this analysis to parametrize the hprobe-based monitors without requiring any user input. Combining the dynamic VM monitoring framework and analysis frameworks allows us to provide on-demand hypervisor based monitors for cloud VMs.

Due to the flexibility of virtualization
there is a good chance that there is a virtual design or system to
meet the most demanding needs and because of this virtualization is
merely duplicating the revolution in open systems by supplying a
wide variety of solutions and meet any IT

▼ The development of
virtualization started in 1960, when VMware introduced partitioning of large mainframes for better hardware utilization. (
Virtualization History, 2010) Since then
virtualization has matured and been adopted to a wide extent in the industry. Recent developments include branching into areas of server
virtualization, storage and application
virtualization and, very recently, desktop
virtualization. Desktop
virtualization has so far been through two models: the Client hosted model, which is typically operated from the user’s workstation using Windows Virtual PC; and the VMware workstation or Java Virtual Machine (VM). However, recently a third model has emerged, called the server hosted model or Hosted virtual desktop (HVD), which is a virtualized form of desktop (VM) delivered to users from the cloud infrastructure. In other words
virtualization in computing has progressed to an extent where desktops can be virtualized and accessed from anywhere. The server hosted model has already surpassed 1% market share of the worldwide professional PC market, with estimates indicating that this is a rapidly growing area.
This study investigates the adequacy of current digital forensic procedures on hosted virtual desktops (HVDs) as there does not appear to be specific methods of locating and extracting evidences from this infrastructure. Using the Forensic Iterative Development Model (FIDM), HVDs deployed in private cloud were simulated to reflect three different computer crime (quasiexperimental) scenarios. It was found that current digital forensic procedures may not be adequate for locating and extracting evidence, since the infrastructure in scenario 2 and 3 introduces complications such as non-persistent disk modes and segregating data in a multitenant environment. However in scenario 1, findings illustrate that all standard investigation techniques can be followed as a result of the persistent user environment. Furthermore, suggestions are made to extend the current research in the areas of techniques to acquire virtual machines from hypervisors, hashing evidence and forensic readiness in environments consisting HVDs.
