I'm trying to get test-kitchen working with a guest Windows VM. I've followed a lot of Matt Wrock's excellent blog posts. I've set up a working Windows Vagrant box, used the right test-kitchen and kitchen-vagrant branches and have managed to get kitchen create to work.

At this point I'm stuck on getting kitchen converge to work. I'll do a converge and run into:

$ kitchen converge
-----> Starting Kitchen (v1.3.2.dev)
-----> Converging <default-windows-7>...
       Preparing files for transfer
       Preparing dna.json
       Resolving cookbook dependencies with Berkshelf 3.1.3...
       Removing non-cookbook files before transfer
       Preparing validation.pem
       Preparing client.rb

At this point I'm at a loss, I'm able to run vagrant up and have the shell provisioner create a file, so the powershell permissions seem to be set correctly. I have more details with all the config files in a gist.
