Thanks to Dugie for the heads up on this announcement, could this be right? everyone is going to co-operate? WOW

DMTF Accepts New Format for Portable Virtual Machines from Virtualization Leaders

New specification created by Dell, HP, IBM, Microsoft, VMware, XenSource aims to become an industry standard; will help ensure portability, integrity and automated installation/configuration of virtual machines

PORTLAND, ORE. September 10, 2007 The Distributed Management Task Force (DMTF®) today announced the acceptance of a draft specification submitted by leading virtualization companies targeting an industry standard format for portable virtual machines. Virtual machines packaged in this format can be installed on any virtualization platform that supports the standard simplifying interoperability, security and virtual machine lifecycle management for virtual infrastructures.

The companies behind the collaboration on this specification include Dell, HP, IBM, Microsoft, VMware, and XenSource. This group of virtualization industry leaders has submitted the specification to the DMTF for development into an industry standard. DMTF is the industry organization leading the development, adoption and promotion of interoperable management initiatives and standards. DMTF will continue to develop this technology into a successful, open industry standard and promote it worldwide.

The proposed format, called the Open Virtual Machine Format (OVF), uses existing packaging tools to combine one or more virtual machines together with a standards-based XML wrapper, giving the virtualization platform a portable package containing all required installation and configuration parameters for the virtual machines. This allows any virtualization platform that implements the standard to correctly install and run the virtual machines.

"With the increasing demand for virtualization in enterprise management, the new spec developed through this industry-wide collaboration dove-tails nicely into existing virtualization management standardization activity within the DMTF," said Winston Bumpus, DMTF president. "OVF extends the work we have underway to offer IT managers automation of critical, error-prone activities in the deployment of a virtualized infrastructure."

Most importantly, OVF specifies procedures and technologies to permit integrity checking of the virtual machines (VM) to ensure that they have not been modified since the package was produced. This enhances the security of the format and will alleviate security concerns of users who adopt virtual appliances produced by third parties. OVF also provides mechanisms that support license checking for the enclosed VMs, addressing a key concern of both independent software vendors (ISVs) and customers. Finally, OVF allows an installed VM to acquire information about its host virtualization platform and run-time environment, which allows the VM to localize the applications it contains and optimize its performance for the particular virtualization environment.

"The impact of OVF will extend far beyond the participating server virtualization vendors to include the entire ISV community. With OVF, an ISV can potentially ship its solutions as a single virtual deployment package that is capable of running on any hypervisor," said Chris Wolf, senior analyst with Burton Group. "OVF marks a new era in virtualization one which includes never-seen-before interoperability in the enterprise. The whole IT community collectively stands to benefit from this landmark standard."

In addition to providing portability, integrity, and configurability of existing virtual hard disk formats. OVF is also extensible to support future developments of virtual hard disk formats whose specifications are openly available.

By collaborating on the development of the OVF specification, the group aims to make it easier for IT organizations to pre-package and certify software packaged as virtual machine templates for deployment in their virtualized infrastructure and to facilitate the secure distribution of pre-packaged virtual appliances by ISVs and virtual appliance vendors. Ultimately, the group's goal is to eliminate the need for IT managers to separately install, configure and manage interdependencies between virtualized operating systems and applications, by enabling automated management of the virtual machine lifecycle.
