Comment 9 for bug 1566358

There is no way we could make a aggregates and extra specs for them and flavors in order to use AggregateInstanceExtraSpecsFilter. It is not a fuel job right now.

In original scenario you've posted there was only one compute, so you need only flavor modification for hugepages.
In case if you want to make mixed setup (w/DPDK and without) in system test, now you could set up aggregates and extra specs by system test code using nova API.

In 10.0 we're try to address this UX.
