Hi Satheera,
the issue is now fixed in Zesty (Development release) and and the Dependency a suggest.
But there is no intention to bring that as a feature back to Xenial.
Especially since the daemon itself is only in universe I'd not consider it all too trustworthy.

I was ok with enabling since it is opt-in and only installed by user (no
hard dependency), but putting that into Xenial would take serious
convincing efforts to the SRU team.

If you want / need that please give it a try
(https://wiki.ubuntu.com/StableReleaseUpdates), but I'm personally not
yet convinced it is worth.

** Also affects: libvirt (Ubuntu Xenial)
   Importance: Undecided
       Status: New

** Changed in: libvirt (Ubuntu Xenial)
       Status: New => Confirmed

** Changed in: libvirt (Ubuntu)
       Status: Triaged => Fix Released

  looks more like a configuration issue, suspecting that libvirt package
  is configured without numa support

  Can Canonical confirm if the libvirt package provides numa support?
