For virtual computers in general, see virtual machine. Oracle VM VirtualBox (formerly Sun VirtualBox, Sun xVM VirtualBox and InnoTek VirtualBox) is a hosted hypervisor for x86 virtualization developed by Oracle Corporation. VirtualBox was originally created by InnoTek Systemberatung GmbH, which was acquired by Sun Microsystems in 2008, which ...
VMDK. VMDK (short for Virtual Machine Disk) is a file format that describes containers for virtual hard disk drives to be used in virtual machines like VMware Workstation or VirtualBox . Initially developed by VMware for its proprietary [ 1] virtual appliance products, VMDK became an open format [ 2][dead link] with revision 5.0 in 2011, and is ...
Type of format. Virtual machine disk image. VHD ( Virtual Hard Disk) and its successor VHDX are file formats representing a virtual hard disk drive (HDD). They may contain what is found on a physical HDD, such as disk partitions and a file system, which in turn can contain files and folders. They are typically used as the hard disk of a virtual ...
Open Virtualization Format ( OVF) is an open standard for packaging and distributing virtual appliances or, more generally, software to be run in virtual machines . The standard describes an "open, secure, portable, efficient and extensible format for the packaging and distribution of software to be run in virtual machines ".
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 hypervisors.
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.
Vagrant is a source-available software product for building and maintaining portable virtual software development environments; [ 5] e.g., for VirtualBox, KVM, Hyper-V, Docker containers, VMware, Parallels, and AWS. It tries to simplify the software configuration management of virtualization in order to increase development productivity.
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.
