Later, a mechanism to set a limit on how much memory may be used for the
overlap prevention structures will be introduced. If that limit is about

+- "start": Offset of the range of clusters (possibly) no longer being
+ checked for writes overlapping with existing metadata.
+ (json-int, optional)
+- "length": Length of that range in bytes. (json-int, optional)

+Example:

+{ "event": "QCOW2_OVERLAP_CHECK_MEMORY_LIMIT_REACHED",
+ "data": { "reference": "virtio0", "start": "805306368",
+ "length": "268435456" },
s/"805306368"/805306368/ and likewise for length (a json-int does not
use quotes).
Oops, right. Will fix.
Otherwise seems okay.
Good, thanks :-)
