如何在不重新启动 openstack 的情况下重新加载 nova.conf

Question

I hava to need to modify the openstack's conf, change the the settings of dnsmasq. It's very easy to reload the config file with restarting nova.network. But, for some reason, I can't do that operation.

so would anyone know how to reload the nova.conf without restarting the openstack?

Also, i can make some changes using code-injections, like add an extension. But I still don't know how to add extension without restarting it?

According to OpenStack docs , to restart Nova service on a controller node (without restarting the server) you should run:

# service nova-api restart
# service nova-cert restart
# service nova-compute restart
# service nova-conductor restart
# service nova-consoleauth restart
# service nova-novncproxy restart
# service nova-scheduler restart
# service nova-spicehtml5proxy restart
# service nova-xenvncproxy restart

On a compute node:

# service nov-compute restart
