Since the situation described is one where the user didn't know they
could/should disable xen, it is reasonable to think they ALSO don't know
they need to exclude virbr0. So, I read the question as meaning the
What happens when a user who doesn't know anything about virbr0 does
mpirun --mca btl_tcp_if_exclude lo,eth8
And my guess is "nothing good happens".
