It was hardly unexpected. Please report the problem to the nfs/rdma list (and keep kvm@ copied, nfs/rdma is fairly relevant to kvm).

Note not all guests support this. -- error compiling committee.c: too many arguments to function -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
