System for Loging Changes in Operating System
Pečeňa, Jan ; Smrčka, Aleš (referee) ; Peringer, Petr (advisor)
Bachelor's thesis describes the design and implementation of applications for the detection of changes in the operating system. Window´s registry, registry key, subkey and value are explained in introductory part. Hash function needed to identify the changed files is explained too. The created application is fully functional and works with 32 and 64 bit versions of Windows. Actual state is saved in the first run. Changes in operating system are detected in the second run. Operating system is installed in a VMWare virtual machine.

Virtualization for the x86 platform
Müller, Pavel ; Kyselý, František (referee) ; Pelka, Tomáš (advisor)
A thesis describes a virtualization of x86 platform. In the first part the virtualization, its utilization and specific types of virtualization are described in a general way. The specific types of virtualization are full virtualization, paravirtualization, virtualization on core level, hardware virtualization and application virtualization. There is also described a general function of virtual machine, reasons of virtualization implementing, current development, focusing on future development and virtualization security. In the second part the thesis tries to find a solution with establishment charges of virtualization. To test purposes the following software programs were used. The first one is freeware benchmark Sandra from SiSoft company and second one is a software created on the basis of the thesis. For the tests the CPU overhead both an arithmetic-logical unit and a unit for work with numbers and floating decimal point, a RAM data transmission efficiency and a hard disk logging rate were chosen. The following test machines were described: VMWare, VirtualBox and Xen. In the third and the last part of the thesis is a description of network interface virtualization methods with a utilization of tun and tap system. In each particular step a virtual network interface creation and implementation are presented. Model situations of communication among virtual and physical machines with usage of these devices are described at the end of the thesis.

The increasing performance of Platform as a Service using virtualization
Schramm, Michal ; Voříšek, Jiří (advisor) ; Sokolovský, František (referee)
This thesis discusses the increasing performance of Platform as a Service using virtualiza-tion. It focuses on the new trends in the provision of IT services, which is virtualization. Possibility of huge savings and improvement of performance of the hardware is interesting for every company, that's why a lot of companies want to migrate to the vir-tual infrastructure. The first part defines IT service and its categories. It describes the development of IT service and brings definitions based on multiple resources. The second part characterizes cloud computing services. This part focuses on the actual composition of the various forms of technology deployments and distribution models. Further focuses on the main benefits and disadvantages of the types of cloud computing. The focus of third part is virtualization. This part presents a five-step procedure for that matter the transition to virtualization. Chapter helps to understand the value that may pose to the enterprise virtualization. The fourth section deals with virtualization in a particular environment. This part brings specific solution of infrastructure virtualization together with the creation of the virtual machine for a new user.

Server consolidation and virtualization
Rybák, Martin ; Bruckner, Tomáš (advisor) ; Zima, Radek (referee)
The thesis deals with the topic of complexity of current IT. As a result, the consolidation of servers using virtualization is the answer to permanently growing complexity of server infrastructure. The thesis summarizes the basic aspects of this issue, compares the contributions and tries to analyze problems which can emerge. Further, it points a way of consolidation journey, compares different types of virtualization and elaborates the contributions of virtualization for corporate IS/ICT and its flexibility of solution. It analyzes present state of the market with virtualization tools, describes and compares some products of the market key players and analyzes the new opportunities for virtualization, e. g. the virtual desktop infrastructure. At the end, it suggests an approach for consolidated project solution in practice and tries to show some basic steps which should not be omitted. Besides the complex view to the topic, the thesis also presents the contributions, risks and questions to be raised and, at least partly, answers these questions.

Virtualization aplication for monitoring networks
Kafka, Jan ; Pavlíček, Luboš (advisor) ; Gála, Libor (referee)
Virtualization is a promising information technology industry today. Whether for reasons of economies, achieve high availability of services, or facilitate the administration etc., gets more and more benefits.With the development of virtualization has been the transition from simple emulation, which was simply procesed as the code processor and simulated a complete computer, the hardware assisted emulation or Paravirtualization make the directing of this process has become almost negligible - literature generally indicates less than three percent. Virtualization also opens the way into the most demanding server applications, where in addition to high availability of services depends also on the optimal use of available hardware resources.The first part is a description of the reasons brought the benefits of deploying a virtualization server environment. The following section discusses virtualization techniques, their characteristics, advantages and disadvantages and most common server virtualization products. In the next chapter are explained the ways to achieve high service availability in a virtualized server environment, and examples of products of VMware, which is the industry leader. Chapter discussed concepts such as cold migration, live migration, technology VMware High Availability, VMware Fault Tolerance, and more. The last chapter is devoted to the practical part of the bachelor thesis. Describes hardware preparation for the experimental environment, the setup, configuration, problems during preparation laboratory network and the installation of dedicated virtualization product, VMware ESX 4.0 64bit. In last part will be describe installation and configuration monitoring software, OpenNMS on server virtualization. At the end, will be examination how fail activities impact on virtualization monitoring software and how rescue this software application VMware ESX 4.0.
