Unlike openvz where all containers can run the same executables and
largely share the same environment, in Xen domU's have nothing in
common except being able to run on the same CPU. "Running an
executable" is inherently domain-specific and thus not something that
Xen should know about.

How about a simple script that given a domain's name or domain ID will
return its IP?
