--- upgrade: - | We have changed the [haproxy_amphora] connection_max_retries and build_active_retries default values from 300 to 120. This means load balancer builds will wait for ten minutes instead of twenty-five minutes for nova to boot the virtual machine. We feel these are more reasonable default values for most production deployments and provide a better user experience. If you are running nova in a nested virtualization environment, meaning nova is booting VMs inside another VM, and you do not have nested virtualization enabled in the bottom hypervisor, you may need to set these values back up to 300. other: - | We have changed the [haproxy_amphora] connection_max_retries and build_active_retries default values from 300 to 120.
