> Yeah, the nova.CONF cpu_allocation_ratio is being overridden to 0.0: The default there is 0.0[1] - and the passing tempest-full from Zuul on https://review.openstack.org/#/c/590041/ has the same line when reading the config[2]: We'll have a dig to see if we can figure out why it's not defaulting to 16 in the ComputeNode.
