For quick designer testing, you can modify nova.conf by altering /opt/platform/armada/19.01/stx-openstack-manifest.yaml on the active controller. Find the openstack-nova schema section and then alter values in data.values.conf.nova: schema: armada/Chart/v1 metadata: schema: metadata/Document/v1 name: openstack-nova data: chart_name: nova release: openstack-nova namespace: openstack … values: … conf: ceph: enabled: true nova: DEFAULT: default_mempages_size: 2048 reserved_host_memory_mb: 0 compute_monitors: cpu.virt_driver Then restart the appropriate pods from platform cli via: system application-apply Gerry From: Winnicki, Chris [mailto:Chris.Winnicki@windriver.com] Sent: Monday, April 08, 2019 1:15 PM To: 张鲲鹏; starlingx-discuss@lists.starlingx.io Subject: Re: [Starlingx-discuss] how to modify nova.conf? StarlingX is a managed system; modifying conf/ini files manually is not supported. All system configuration changes should be done via: nova, openstack, neutron, system, cinder, etc....

Hi All， In some case, I need to modify /etc/nova/nova.conf. But it will recover to original after reboot. Are there some way to persist nova.conf? Thanks Kunpeng
