Configure a Live Migration Completion Timeout in NovaΒΆ

You can configure how long to allow for a compute live migration to complete before the operation is aborted.

The following example applies a timeout of 300 seconds to all hosts.

The same basic workflow of creating an overrides file, then using it to update helm overrides for the application, and finally reapplying the application to make your changes effective can be used to apply other Nova overrides globally.


  1. Create a yaml configuration file containing the configuration update.

    ~(keystone_admin)]$ cat << EOF > ./nova_override.yaml
          live_migration_completion_timeout: 300
  2. Update the Helm overrides using the new configuration file.

    ~(keystone_admin)]$ system helm-override-update --values ./nova_override.yaml stx-openstack nova openstack --reuse-values
  3. Apply the changes.

    ~(keystone_admin)]$ system application-apply stx-openstack
