The question came up in the comments about using ova format with rhevm-image-uploader. (https://access.redhat.com/articles/67891) The Administration Guide does not mention ova files at all. It would be good to declare somewhere (16.4. The Image Uploader Tool) that ova files are basically an ovf package stored as a TAR archive, and work with the uploader tool.
Assigning to Byron for review. Users can use the engine-image-uploader tool to upload both OVF and OVA files, but only OVF is mentioned in the documentation; OVA files should be mentioned alongside OVF, and a brief description of the difference between the two should be added.
