When listing snapshot with VIR_DOMAIN_SNAPSHOT_LIST_NO_METADATA, it
always returns 0 or no snapshot. Because we never implement funtions
to list no-metadata snapshot in virDomainSnapshotObjListGetNames():
if ((data.flags & VIR_DOMAIN_SNAPSHOT_FILTERS_METADATA) ==
VIR_DOMAIN_SNAPSHOT_LIST_NO_METADATA)
return 0;
Add notes for that flag.
Please update the comment and man page of that flag when no-metadata
snapshot list is implemented in the future.
