Amit, thanks for the quick response. Not sure what you mean by "BFV" ? After your comments, I was able to make a little progress. I hadn't looked at the logs on the compute notes prior to that, I was only looking on the controller. I saw an error related to the compute note trying to make a connection to the database. I made that fix in the nova.conf on the compute nodes, and now when I spin up a new instance, the volume does correctly show "in-use" and that it is attached to the instance :-) However, I am still getting some errors that I don't know what to do with. On the controller, I am seeing a bunch of these: /var/log/nova/nova-metadata-api.log:2024-09-11 09:59:51.273 560137 ERROR nova.api.metadata.handler [None req-799be5d5-5a00-4eb9-a90b-8561f73949ab - - - - - -] Failed to get metadata for instance id: f3a05784-7404-4319-b878-d40538bf152d: keystoneauth1.exceptions.http.Unauthorized: The request you have made requires authentication.

On a positive note, when trying the migrate, I did find/fix an error in my sudoers config, and now I am able to live migrate, so it is just the snapshot error that I am trying to fix currently.
