There is coming trend of virtualization on modern computers. One computer may act like host for several guest virtualized computers. This has many advantages, like for kernel development, software testing, virus behaviour testing, saving HW resources. On the other hand, complexity of computer maintenance is growing too. This bachelor thesis describes a system, that can be used for management of many virtual servers and lower the manageability overhead. This work will create a generic control interface for virtualized computers. Interface will be adaptable and extendible. The development of this system is described from specification through analysis to concept and implementation of application
