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

This is the officially-supported way of changing the configuration. Chris On 4/8/2019 2:41 PM, Liu, Yang wrote:

Or update the helm override. Example:

system helm-override-update --set conf.nova.DEFAULT.default_mempages_size=<new_value> nova openstack

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

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*
