With it's limited ability, it seems to be working. But we're working on the vCloud module now since there's just too much manual intervention required to use the vmware5 module. It does automatically provision and suspend, and plugs directly into vCenter server so you can pick and choose the hosts, datastores, and iso images, but it's a nightmare creating hundreds of order pages to support every single possibile configuration and OS so the vCloud module is the way to go.
