Packer build using vmware-iso\ESX, post processor to vagrant\virtualbox possible?

Hi

I’m new to Packer and currently using vmware-iso and esx to build my images.

For local testing i now want to use a post-processor to output a .box file that will work with virtualbox and vagrant. is this possible? is there any examples i can reference?

I added “provider”: “virtualbox” to my post-processor but this throws an error :frowning:

Thanks
Stephen
