Since the situation described is one where the user didn't know they

That's what I'm thinking.
So, I read the question as meaning the following:
What happens when a user who doesn't know anything about virbr0 does
mpirun --mca btl_tcp_if_exclude lo,eth8
I'm not sure I understand your question -- the above will exclude loopback and
eth8.
(where did eth8 come from?)
Sorry, if I wasn't clear.
I'll try again:
+ User knows nothing about xen, and thus nothing about virbr0
+ User has a local-only interface (eth8 in my made up example)
+ User reads FAQ entry "220. How do I tell Open MPI which TCP networks
to use?"
+ User follows instructions given in said FAQ, yielding my example
command line.
