Problem

For VMs provided at https://developer.microsoft.com/en-us/microsoft-edge/tools/vms/ on the Vagrant "platform", the provided ZIP file does not meet the Vagrant box file format specification detailed here: https://www.vagrantup.com/docs/boxes/format.html

Specifically, when using an archive (tar, tar.gz, zip, etc.) a metadata.json file must be included and:

metadata.json must contain at least the "provider" key with the provider the box is for.
{ "provider": "virtualbox" }

Solution

1. Include the aforementioned metadata.json file
   or
2. Provide the Vagrant "platform" option as the raw .box file and NOT as an archive (also worth mentioning the current ZIP is adding nothing in terms of compression and instead adds 195 bytes)

Thanks!
