You can import an Open Virtualization Format (OVF) virtual machine and run it in Workstation Player. Workstation Player converts the virtual machine from OVF format to VMware runtime (.vmx) format. You can import both .ovf and .ova files.
OVF is a platform-independent, efficient, extensible, and open packaging and distribution format for virtual machines. For example, you can import OVF virtual machines exported from VMware Fusion™ or Oracle VM VirtualBox into Workstation Player. You can import OVF 1.x files only.
You can also use the standalone OVF Tool to convert an OVF virtual machine to VMware runtime format. The standalone version of the OVF Tool is installed in the Workstation Player installation directory under OVFTool. See the OVF Tool User Guide on the VMware Web site for information on using the OVF Tool.
