Hum if I understand well and according your issue reported to
launchpad.net

  https://bugs.launchpad.net/nova/+bug/1417201

You are trying to test hugepages under kilo which it is not possible
since it has been implemented in this release (Juno, not yet
published)

I have tried to reproduce your issue with trunk but I have not been
able to do it. Please reopen the bug with more information of your env
if still present. I should received any notification from it.

Thanks,
s.
