Manažment a rezervácia zdrojov pre OpenStack virtualizáciu pomocou nástroja ViRo v3

This diploma thesis is focused on analyzing current state of OpenStack virtualiza-tion, resource management and reservation of physical resources of server for virtualization tool GNS 3 in ViRo-v3 (updated to ViRo-v3.1). Next part of this work solves the method-ology of ViRo-v3.1 tool development, which manage the rest of the work. In the practical part of this work is dedicated to the implementation of resource management for the OpenStack virtualization tool as well as the reservation of physical resources in this case for both GNS 3 and OpenStack virtualization tools on the server side using an existing pro-posal with possible modifications. In addition, other partial parts are implemented as import and export topology or backup of network devices. A user interface for implemented reser-vation of physical resources is implemented on the client side, where users will be able to create a reservation of physical resources or in the case of an administrator view existing reservations. The last part of this work is focused on testing and verifying the functionality of implemented functions.
