These are some personal notes for converting various VM types into others. Use these notes if you've built a machine from an ISO, OVA, etc and would like export it to use with with Virtualbox or VMWare.
Conversion process can be done with the built-in VMWare Workstation Player binary: OVFTool.
Converting one image to another is as simple as calling the binary, providing the input, then the output.
For example you've built up a VMWare image and would like to export.VMX to .OVA
Simple as that.
