And no state of the <domain> at the time the checkpoint was created?
I meant to add:
once we start playing with checkpoints vs. external snapshots vs.
hotplug in anger, then knowing WHICH disks existed at the time of a
given checkpoint may prove invaluable to even figure out WHICH disks
need to participate in a given backup operation. The initial
implementation uses XML (so that adding features can hopefully reuse the
same API, rather than needing yet more one-off API additions), even if
it is currently limited to not playing nicely with snapshots.
