29、secure, por-table, efficient and extensible format for the packaging and distribution of software to be run in virtual machines. The key properties of the format are as follows: - Optimized for distribution: OVF supports content verification and integrity checking based on industry-standard public k

30、ey infrastructure, and it provides a basic scheme for management of software licensing.- Optimized for a simple, automated user experience: OVF supports valida-tion of the entire package and each virtual machine or metadata component of the OVF during the installation phases of the virtual machine (

31、VM) lifecycle management process. It also packages with the package relevant user-read-able descriptive information that a virtualization platform can use to stream-line the installation experience. - Supports both single VM and multiple-VM configurations: OVF supports both standard single VM packag

32、es and packages containing complex, multi-tier services consisting of multiple interdependent VMs.- Portable VM packaging: OVF is virtualization platform neutral, while also en-abling platform-specific enhancements to be captured. It supports the full range of virtual hard disk formats used for hype

33、rvisors today, and it is exten-sible, which allow it to accommodate formats that may arise in the future. Vir-tual machine properties are captured concisely and accurately.- Vendor and platform independent: OVF does not rely on the use of a specific host platform, virtualization platform, or guest o

34、perating system.- Extensible: OVF is immediately useful - and extensible. It is designed to be ex-tended as the industry moves forward with virtual appliance technology. It also supports and permits the encoding of vendor-specific metadata to sup-port specific vertical markets.- Localizable: OVF sup

35、ports user-visible descriptions in multiple locales, and it supports localization of the interactive processes during installation of an ap-pliance. This capability allows a single packaged appliance to serve multiple market opportunities.- Open standard: OVF has arisen from the collaboration of key

36、 vendors in the industry, and it is developed in an accepted industry forum as a future stan-dard for portable virtual machines.It is not an explicit goal for OVF to be an efficient execution format. A hypervisor is allowed but not required to run software in virtual machines directly out of the Ope
