Could you run nova-manage cell_v2 discover_hosts and try again?

Additionally, could you upload packstack logs in /var/tmp/packstack/latest/manifests/*log?

[Eric Fried (efried)]

Not sure if adding "affects nova" is entirely appropriate, but we encountered this when testing this patch with the PowerVM driver: https://review.openstack.org/443189 which is currently based on commit 80af8a9dacf6fbd853b5b0e07ffb8bffac3aa8fa of the nova tree.

After I ran the nova-manage command suggested by amoralej in comment #2, I was able to proceed.

https://docs.openstack.org/developer/nova/cells.html we had similar issue in multinode env, we referred to that document and fixed the problem, so no target to nova I guess
