Is there a vendor-independent standard for VMs that solutions providers can refer to before performing a virtual machine migration?
Because each vendor is competing with one another, there has not been a strong push to have a universal format that all hypervisors can use. An Open Virtualization Format (OVF) was proposed by all of the leading vendors but was more a universal method of packaging and distributing VMs than an actual virtual machine file standard. The OVF uses .xml files to describe the configuration of a VM and is not specific to virtual disks, which remain proprietary to each specific vendor. Today, the OVF is mainly used for importing and exporting VMs to any of the hypervisors that support it.
