Connecting RTOS with GPOS in industrial use
Thér, Tomáš ; Dobrovský, Ladislav (referee) ; Lang, Stanislav (advisor)
This thesis explores the integration of real-time operating systems (RTOS) and general-purpose operating systems (GPOS) in industrial automation. RTOS are crucial for deterministic control of critical processes, while GPOS offer a wide range of tools. The thesis focuses on the exOS product from B&R, detailing its features, installation, and development tools. Finally a model application is created, implementing a database for a plasma cutter in a real industrial project.

Svída, Dominik ; Dudek, Tomáš (referee) ; Ondrák, Viktor (advisor)
In my bachelor´s thesis I deal with an issue of extension of virtual platform in a great company. In the first part of my thesis I work with familiarization with the company and analysis of the actual IT structure. The second part is theoretically focused on area of virtualization, reasons for usage and types of virtualization. Furthermore, I describe the most used platforms from Microsoft and VMware companies, in addition I compare them. The last part of my thesis is about a proposal of the most suitable solution and a total evaluation of benefits for the company.

Virtual environment by Xen software
Kulíř, Tomáš ; Kouřil, Jiří (referee) ; Jelínek, Mojmír (advisor)
This bachelor thesis, which is called the virtual environment by Xen software, deals with the operating system GNU / Linux and its distributions. It also deals with the virtualization on the server or desktop computer, in particular, describes in detail the Xen environment, including all of its options and the most forgotten server services. In the first chapter is analyzed the concept of GNU / Linux. First, there is documented history. Another section deals with a brief overview of the most commonly occurring distributions. The main part of this chapter is primarily devoted to a specific distribution Debian. There is described not only the history and development of this distribution, but also more packaging system is analyzed there. The last part of this chapter is devoted to the installation options with a detailed description of the whole process step by step. Second and the most important chapter is devoted to virtual environments. Once again, there is first described their history, the possibility of practical use and the types of virtualization are also indicated there. Reader will find there a brief analysis of the most commonly used virtualization systems. The third chapter detailed deals with the Xen technology. There is not only explained the principle on which the virtualization is built, but the main part of this chapter focuses on the practical use and a summary of basic functions. The next section describes the installation and administration of hypervisor including previous preparation. A very important point is also creation of the virtual machines and their control, their migration to another physical hardware or a description of the installation of other operating systems than Linux. Fourth, shorter chapter deals with a listing and a brief description of server services. The final chapter consists of a summary of problems or complications, which in the course of this work occurred.

Deploying Virtual Servers for ISP
Zelený, Jan ; Michal, Bohumil (referee) ; Kašpárek, Tomáš (advisor)
This thesis describes principals of virtualization based on the Xen project. Text focuses mainly on putting system into service for purpose of it's subsequent use by ISPs. The goal of this work is also to explore the possible usages of virtualized systems based on the Xen by ISPs. One of these possibilities will be specified to the point when it will by usable or it will be able to be developed independently of author of this work. This work also designs and mostly implements system, which can be used as a base for wide spectrum of of services, when installing these services doesn't effect the rest of the system.

Libvirt Admintration API
Škultéty, Erik ; Peringer, Petr (referee) ; Smrčka, Aleš (advisor)
Tato práce se zabývá problematikou virtualizace, konkrétně virtualizační knihovnou libvirt, cílem které je správa virtuálních strojů a podpora různých typů hypervizorů a virtualizačních řešení jednotným způsobem transparentním pro uživatele. Podstatná část funkcionality knihovny libvirt je na pozadí implementována formou démona libvirtd. Ačkoliv libvirtd démon poskytuje služby pro správu virtuálních strojů, neumožňuje správu sebe samého, kromě změn hodnot parametrů v konfiguračním souboru. Pro změnu nastavení je pak standardním přístupem změna v konfiguračním souboru a následný restart démona. Jelikož uvedený způsob mění pouze perzistentní konfiguraci a restart démona nemusí být vždy optimální řešení, vznikla idea administrativního rozhraní knihovny libvirt, které by umožnilo správu démona za běhu. Hlavním přínosem této práce je návrh a popis implementace aplikačního rozhraní pro administraci knihovny libvirt. Konkrétně pro tuto práci byla zvolena rozhraní pro konfiguraci počtu obslužných vláken, nastavení úrovně a filtrovacích parametrů pro žurnálovací podsystém a správu připojených klientů na straně démona libvirtd.
