Emulation virtualization computer literature training materials (Link to this page as [[QEMU-KVM-Buch / eneral / Introduction]]) | # # # | >>> | English Introduction Virtual machines provide defined system environments. For templates with a specific version of an operating system and a desired patch level virtual machines are generated. Snapshots save states of a virtual machine. When an unwanted change can be restored to their former condition. Virtuali ation and emulation allow the independence of the hardware. Thus, for example, to run old versions of an application to develop new hardware or software for non-existing hardware. These are the strengths of %EMU. %EMU is free and runs on many systems (Linux, BSD, Mac ,S -, Microsoft Windows, e.omStation or D,S/. Virtuali ation brings a number of advantages, depending on the type are weighted differently. 0iven that several guest systems can run on a parallel computer, increases hardware utili ation is possible. 1reviously, for critical applications used in each case a physical computer. The result is a large machine par2 with a correspondingly high cost (ac3uisition, maintenance, power, air conditioning/. If, however, individual applications running in a virtual machine, the applications are decoupled from each other and the hardware is better utili ed. Besides security, the availability is increased, because virtual machines can be transferred in case of hardware problems on a different hardware. This optimi ation of the data center through virtuali ation solutions are called server consolidation. The 5ernel-based Virtual Machine (5VM/ is an appropriate virtuali ation solution. 5VM is open source and runs on Linux. The management of virtual machines is done under different virtuali ation solutions is very different. In a heterogeneous data center, it is often impossible to control with a tool more virtuali ation solutions. To solve this problem, the . library is designed libvirt. It provides standard interfaces for managing different virtuali ation solutions.

The Hypervisor is the one which provides the complete virtualization environment which will intend to virtualize as much as hardware and systems which will include the CPUs, Memory, network interfaces and so on. Because of the virtualization technologies such as the KVM and others such as ESXi, there has been a significant decrease in the usage if the resources and decrease in the costs involved.
