These two separate case config[:provider] blocks setting p.name should be consolidated into a single case statement. This would improve code maintainability and follow the pattern used elsewhere in the file.

Consider merging them like this:

<% case config[:provider]
   when "virtualbox" %>
    p.name = "kitchen-<%= File.basename(config[:kitchen_root]) %>-<%= instance.name %>-<%= SecureRandom.uuid %>"
<% when "tart" %>
    p.name = "kitchen-<%= File.basename(config[:kitchen_root]) %>-<%= instance.name %>"
<% end %>
