On all distributions, you must perform some final tasks to complete the upgrade process.
Decrease DHCP timeouts by modifying
/etc/nova/nova.conf on the compute nodes
back to the original value for your environment.
Update all .ini files to match
passwords and pipelines as required for Havana in your
environment.
After a migration, your users see different results from
nova image-list and glance
image-list unless you match policies for access to
private images. To do so, edit the
/etc/glance/policy.json and
/etc/nova/policy.json files to contain
"context_is_admin": "role:admin", which limits
access to private images for projects.
Thoroughly test the environment. Then, let your users know that their cloud is running normally again.
