I just found it relevant to point out that historical Wiki on Live snapshot= s were approaching this with the external-first in mind - when I look at revisions [1], already in 2011: "Internal snapshots to images which support internal snapshots (QCOW2 & QED= ) are not expected to be supported initially." > That mean that we don't have a clean snapshot solution currently for > shared san/nas without api. And that it is overdue at least since 2017 (the original forum attempt at discussion, not mine). Anyhow, good that is now being reviewed. There's enough interested in the s= aid forum for this already. NB I don't believe I should have been asked to take that supporting input elsewhere.
