Description Gregory Charot 2020-10-07 16:05:58 UTC
Description of problem:

DCN 16.1 we introduced ceph at the edge. The DCN doc mentions that a glance image copy must be present on the site's ceph cluster before an instance can be booted on a given site.

If the user forgets to copy the image to the site before booting the VM, nova will download the image from glance in central site (raw) and upload it to ceph itself.

This is highly inefficient and user is not notified of this process.  

In order to prevent this, we would like to backport the following patch, that prevents nova to behave this way.
