Hi all,

numad provides dynamic and advisory NUMA tuning. It monitors NUMA
topology and cpu/memory usage within a system and dynamically tunes
NUMA and CPU affinity and/or provides process pre-placement advice to
management tools like libvirt. If you've never tried it, it works very
well and can improve performance markedly.

Ubuntu has started packaging numad for Xenial, which is exciting for
those of us that don't like running a custom-compiled libvirt on our
clouds... But unfortunately Xenial libvirt isn't currently compiled
with numad support. If you want this feature too then please go +1
this bug:
