scheduler_default_filters=AllHostsFilter ram_allocation_ratio=3.0 Regards, On Thu, May 12, 2016 at 10:50 AM, Nasir Mahmood <[email protected]> wrote: > If this is not a production setup, try recreating or updating your nova db > > su -s /bin/sh -c "nova-manage db sync" nova > > And then restart all relevant services on controller node. > > Irfan, > > You compute host might not be able to communicate with the controller > node.
