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".
Virtual appliances are provided to the user or customer as files, via either electronic downloads or physical distribution. The file format most commonly used is the Open Virtualization Format (OVF). It may also be distributed as Open Virtual Appliance (OVA), the .ova file format is interchangeable with .ovf.
Virtual appliances distributed as virtual machine types such as: Open Virtualization Format (OVA) - As of v14.0 was the default VM format. It supports VirtualBox and most VMware products (e.g. Workstation, Player, Fusion and vSphere/ESX). Also includes open-vmtools (for VMware).
VMware provides a semi-automated tool called VMware vCenter Converter for moving physical servers running Windows or Linux into virtual environments while they are powered on. VMware vCenter Converter replaces two older utilities: Importer (bundled with VMware Workstation) and P2V Assistant.
vCenter Server Appliance (VCSA) is the centralized management utility for VMware, and is used to manage virtual machines, multiple ESXi hosts, and all dependent components from a single centralized location. VMware vMotion and svMotion require the use of vCenter and ESXi hosts.
VMware vSphere (formerly VMware Infrastructure 4) is VMware's cloud computing virtualization platform. [ 2 ] It includes vCenter Configuration Manager, as well as vCenter Application Discovery Manager, and the ability of vMotion to move more than one virtual machine at a time from one host server to another.
The VMware Infrastructure suite allows enterprises to optimize and manage their IT infrastructure through virtualization as an integrated offering. The core product families are vSphere, vSAN and NSX for on-premises virtualization. [1] VMware Cloud Foundation (VCF) is an infrastructure platform for hybrid cloud management. [1]
A flat image allocates space ahead of time while a sparse image grows as the virtual machine writes to it. Flat images can use the underlying file system's sparse file capability, as is done with the vmfs format on ESXi. An image can also refer to a parent image and only store changes made in a copy-on-write fashion. This enables creating a ...
