Yes and no. The current implementation transfers a configuration file that's essentially the state of the domain (represented in S-Expressions). Reading in that state will likely result in the execution of certain scripts. I can certainly imagine scenarios where you would want to define a script that's associated with the bring-up of a VM and that you would need some mechanism to marshall up the script and send it along with the VM. This introduces all sorts of interesting problems though. Basically, I don't think configuration migration is a solved problem yet. It's something I want to explore in vm-tools.
