@choleowsky
this is a regression issue by 4627fb2
@skattoju3 can you please have a look at #3884 ?
for NFS, we should check by path not uuid as well, similar as #3181

I found a wrkaround that seems to indicate where the problem lies.
From what I have seen, the LibvirtStoragePool.getPhysicalDisk procedure goes to look for the files of the migrated volumes with the value of the "path" column of the "volumes" table.
When a volume is migrated from one storage to another, the "path" field is changed but the LibvirtStoragePool.getPhysicalDisk procedure seems to go looking for the volume with its old "path" which now corresponds to the "uuid" field.
If I make a symbolic link directly in the new NFS storage server's filesystem (ln -s <path> <uuid>), after some time I found that metrics were updated and the message in agent.log no longer appeared.
