Currently the clusters function in app/models/compute_resources/foreman/model/vmware.rb maps the full_path. This only works when the cluster name is the same as the cluster full_path.
All references in Fog to retrieve cluster information relies on the cluster name not the cluster full path.

I get the following failed to create vm: undefined method `resourcePool' for nil:NilClass when trying to pass the cluster full_path. Changing the clusters function in app/models/compute_resources/foreman/model/vmware.rb to map to name instead fixes this issue.
