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.

Virtualization in IS/ICT
Naiman, Michal ; Gála, Libor (advisor) ; Kašpar, Jaromír (referee)
The goal of the thesis is to examine and assess actual portfolio of products on the market for server visualization and to compare performance of individual products with performance of the physical machine. The research and the assessment of the actual portfolio will be carried out with the focus on current trends in the area of server virtualization, reasons for realization, and important aspects for their successful implementation. The comparison will be carried out in areas of supported platforms, hardware emulation spectra, hardware limitations, licensing and prices. Further it will be performed comparison in the form of benchmark performance in areas of CPU, RAM, hard-drive throughput, and network throughput of most commonly used products for server virtualization.
