Kernel-based Virtual Machine (KVM) is a free and open-source virtualization module in the Linux kernel that allows the kernel to function as a hypervisor. It was merged into the mainline Linux kernel in version 2.6.20, which was released on February 5, 2007. [1] KVM requires a processor with hardware virtualization extensions, such as Intel VT ...
A KVM Switch is a hardware device used in data centers that allows the control of multiple computers from a single keyboard, monitor and mouse (KVM). [6] The switch allows data center personnel to connect to any server in the rack.
Rackmount KVM. Rackmount lay-flat KVM. A KVM is a computer input/output device offering the combination of a keyboard, video monitor and mouse (pointing device). They are typically constructed to fit into a 19-inch rack although there are manufacturers who offer a KVM that can be mounted to a flat surface such as a control console.
Virtualization. In computing, virtualization (v12n) is a series of technologies that allows dividing of physical computing resources into a series of virtual machines, operating systems, processes or containers. [ 1 ] Virtualization began in the 1960s with IBM CP/CMS. [ 1 ] The control program CP provided each user with a simulated stand-alone ...
Hypervisor. A hypervisor, also known as a virtual machine monitor (VMM) or virtualizer, is a type of computer software, firmware or hardware that creates and runs virtual machines. A computer on which a hypervisor runs one or more virtual machines is called a host machine, and each virtual machine is called a guest machine.
Contents. Comparison of platform virtualization software. Platform virtualization software, specifically emulators and hypervisors, are software packages that emulate the whole physical computer machine, often providing multiple virtual machines on one physical platform. The table below compares basic information about platform virtualization ...
x86 virtualization. x86 virtualization is the use of hardware-assisted virtualization capabilities on an x86/x86-64 CPU. In the late 1990s x86 virtualization was achieved by complex software techniques, necessary to compensate for the processor's lack of hardware-assisted virtualization capabilities while attaining reasonable performance.
Server room. A server room in Písek, Czech Republic. A server room is a room, usually air-conditioned, devoted to the continuous operation of computer servers. An entire building or station devoted to this purpose is a data center. The computers in server rooms are usually headless systems that can be operated remotely via KVM switch or remote ...
