I am trying to export a server from on premise ESX environment to vCloud Director on a hosted ESX platform. I noticed that you can only import ovf files into vCloud Director, my understanding is that a ovf export is made up of multiple (.ovf / .vmdk / .mf) files where as an ova is a single file export. If vCloud Director doesn't support the upload of ova's how do you get a single ovf file that includes the vmdk's and mf files ?
