25、tandard INCITS 469-2015.)The Open Virtualization Format (OVF) Specification describes an open, secure, effi-cient, and extensible format for the packaging and distribution of software to be run invirtual systems.The OVF package enables the authoring of portable virtual systems and the transportof vi

26、rtual systems between virtualization platforms. The key properties of the formatare as follows: - Optimized for distribution: OVF supports content verification and integ-rity checking based on industry-standard public key infrastructure, and itprovides a basic scheme for management of software licen

27、sing.- Optimized for a simple, automated user experience: OVF supportsvalidation of the entire package and each virtual system or metadatacomponent of the OVF during the installation phases of the virtual system(VS) lifecycle management process. It also packages with the packagerelevant user-readabl

28、e descriptive information that a virtualization plat-form can use to streamline the installation experience. - Supports both single VS and multiple-VS configurations: OVF sup-ports both standard single VS packages and packages containing com-plex, multi-tier services consisting of multiple interdepe

29、ndent VSs.- Portable VS packaging: OVF is virtualization platform neutral, while alsoenabling platform-specific enhancements to be captured. It supports thefull range of virtual hard disk formats used for hypervisors today, and it isextensible, which allows it to accommodate formats that may arise i

30、n thefuture. Virtual system properties are captured concisely and accurately.- Vendor and platform independent: OVF does not rely on the use of aspecific host platform, virtualization platform, or guest software.- Extensible: OVF is immediately useful - and extensible. It is designed tobe extended a

31、s the industry moves forward with virtual appliance tech-nology. It also supports and permits the encoding of vendor-specificmetadata to support specific vertical markets.- Localizable: OVF supports user-visible descriptions in multiple locales,and it supports localization of the interactive process

32、es during installationof an appliance. This capability allows a single packaged appliance toserve multiple market opportunities.- Open standard: OVF has arisen from the collaboration of key vendors inthe industry, and it is developed in an accepted industry forum as a futurestandard for portable vir

33、tual systems.It is not an explicit goal for OVF to be an efficient execution format. A hypervisor is al-lowed but not required to run software in virtual systems directly out of the Open Vir-tualization Format. This standard contains seven annexes. Annex B is normative and is considered partof this
