If you are trying to use OMPI as the base for ORCM, then you can tell ORCM
to use OMPI's "tcp" multicast module - it fakes multicast using pt-2-pt tcp
messaging.
-mca rmcast tcp
will do the trick.

I'm still not sure what you're asking -- are you asking how to get Open MPI to
work if multicast is disabled in your network?
If so, not to worry; Open MPI doesn't currently use multicast.

I'm not sure what you're asking. Open MPI should work just fine in a Xen
environment.
If you're unsure about how to use the MPI API, you might want to take a
tutorial to get you familiar with MPI concepts, etc. Google around; there are a
bunch available. My personal favorite is at the UIUC NCS
