Detached VM Snapshots after Warm Migration
-
I recently migrated all my VMs to new hosts in a new pool via warm migration, which worked great, but I am now seeing "detached snapshots" for the VMs that I moved. I have tested on another VM which was created natively on one of the new hosts and it does not have the same problem.
It says it has a "Missing VM":
I also recently migrated from a Xen Orchestra container to another (x86 -> ARM), but unsure if that has anything to do with it - I restored my XO config from a metadata backup. The natively created VM was made after this move.
Is there something I need to do or re-configure to prevent this? The snapshots appear to work, but I have not yet tried to revert to one.

Looked at some other posts, it seems it probably does have something to do with my old XO. This is no longer active, can I re-associate the VMs with my current XO instance? I imported my config from a backup, so I thought that would cover it, my new XO instance spun up exactly like the old one.
Broken snapshot (logs show it initiated from the pool master's IP):

OK, I still had my old pool master registered as a server in XO (disabled), removing this and restarting XO now shows the VMs properly in the audit logs when snapshot, and it shows them being initiated by my XO IP, but the snapshots are still seen as detached ("Missing VM").
Maybe it will just resolve itself eventually if XAPI is holding onto stale references? I still have my old backups ("Detached backups") that I'm waiting to remove (job itself removed), maybe that's also impacting things - I will be removing the backed up VHDs once my NAS has copied them to an external drive (very slow!).
I'm not opposed to blowing XO away and starting it over, I need to start a new backup job anyway - if there's a procedure/best practice to go by in order to re-create all the metadata I'd be interested.
