I'm going to update the status of this bug as wontfix per comments
regarding Cellsv1 freeze above. If you find further information that
suggests this is unrelated to Cellsv1 then feel free to reopen this bug
with that new information.
** Changed in: nova
Status: Confirmed => Won't Fix
** Summary changed:
- Can't create instances with flavors that have "numa" related extra specs in a
cell setup
+ Can't create instances with flavors that have "numa" related extra specs in a

Reproduce steps:
1) Setup nova in order to use cells.
2) Create a flavor with the extra spec "hw:numa_nodes"
nova flavor-create m1.nano.numa2 30 64 1 1
nova flavor-key 30 set hw:numa_nodes=1
3) Create an instance with the new flavor
Actual Result:
Instance status: ERROR
Instance task state: scheduling
Trace in "child cell".
Tested in devstack (master).
Tested in Kilo.
