Wow, 6 months with no reply on this.
I need the same functionality to avoid becoming a vmware customer. We have a bunch of Mac notebooks here, all running Parallels, but I need to have a bunch of vm's available over RDP for testing purposes.
Converting VMs between VMWare and Parallels whenever I need to move one from the servers to a notebook is a non-starter, which I'm afraid is going to force me into VMWare's arms.
Is there no way to run Parallels on Linux "headless"?
