While I realize my reply is a little late, I'd still like to raise the question
about the tools side not coping with the new default - I would think
that any default setting ought to imply that (within the scope of a
project) the whole software stack should still work. At the very
minimum CPU affinity changes (default settings on NUMA as well as
manual ones through xm) do not presently work for CPUs beyond 64.
