Since VirtualBox version 5.1.30, [29] Oracle defines personal use as installation on a single computer for non-commercial purposes. [30] Prior to version 4, there were two different packages of the VirtualBox software. The full package was offered gratis under the PUEL, with licenses for other commercial deployment purchasable from Oracle.
VHDs are implemented as files that reside on the native host file system. The following types of VHD formats are supported by Microsoft Virtual PC and Virtual Server: Fixed hard disk image: a file that is allocated to the size of the virtual disk. Fixed VHDs consist of a raw disk image followed by a VHD footer (512 or formerly 511 bytes). [2]
Some live CDs can save user-created files in a Windows partition, a USB drive, a network drive, or other accessible media. Live backup CDs can create an image of drives, and back up files, without problems due to open files and inconsistent sets. A few additional uses include: installing a Linux distribution to a hard drive; computer forensics
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.
Distributed file system: any file system that allows access to files from multiple hosts sharing via a computer network; Virtual file system: an abstraction layer on top of a more concrete file system, allowing client applications to access different types of concrete file systems in a uniform way
In computing, a virtual machine (VM) is the virtualization or emulation of a computer system. Virtual machines are based on computer architectures and provide the functionality of a physical computer. Their implementations may involve specialized hardware, software, or a combination of the two.
It is a way to abstract away the physical details of storage and allow files to be stored on any type of storage device, without the need for specific drivers or other low-level configuration. File-based virtualization can be used for storage consolidation, improved storage utilization, virtualization and disaster recovery. This can simplify ...
Application virtualization is a software technology that encapsulates computer programs from the underlying operating system on which they are executed. A fully virtualized application is not installed in the traditional sense, [1] although it is still executed as if it were.
